Lighter bullets must travel faster than heavier bullets to reach the same power factor and therefore require more gunpowder. We're taking a look at what the Army's Elite Units are using for service rifles and what the future of SOCOM sniping looks like. Give a Gift   and 223 Rem. The .45 ACP TRP firing a 230-grain bullet at 880 feet per second generates 5.43 foot-pounds of energy. The bullet wgt vs recoil issue is based on like PF/loads/impact-I guess. So the area in inches is (3.14159*(.355^2))/4 = 0.099 in^2. I am thinking of stocking up 1000 rounds free shipping on 9mm 124GR. When shooting rifles at longer distances, bullet weight becomes more important. 30-06 Springfield 125 gr SST® Custom Lite® Item #81066 | 20/Box . Bullet grain (gr) refers to the weight of the bullet and not the whole cartridge. All Palmetto Reloading Gear/Accessories! If you are not familiar with the composition of a cartridge, here’s a quick explanation of these four parts: Primer: The part of a cartridge that is struck by the firing pin, creating a small explosion that ignites the powder, Powder: Fast-burning propellant that is ignited by the primer explosion; the gases released create a pressure in the case that pushes the bullet out, Case: Brass, aluminum, or steel container that houses the primer and powder while the bullet is seated in the open end; sometimes referred to as shells or brass, Bullet: The projectile that leaves the barrel of the gun and moves toward your target. Ultimately, find a cartridge that performs well under testing or real world applications and most importantly, one that functions well in your gun. So now we know that there are different weights for bullets and that this is measured in grains. Because heavy bullets generally travel at a slower velocity and don’t rotate as fast, they can be harder to stabilize than a lighter, faster moving bullet. Shooters differ on which they prefer. Does it make a difference if you're carrying 9mm 147-grain or 115-grain? We ping steel with a .300 WinMag at over a mile. The 115 grain bullet produces 3.38 ft lbs of recoil force, the 147 grain bullet produces 3.18 ft lbs of recoil force. Velocity, energy, and even the burn rate of the specific powder used can contribute to differences in felt recoil. Feb 2, 2014 #1/10 After 5 or so years of using moly coated lead 230 RN bullets in my XD45, I've finally exhausted my supply of components and I'm looking to restock. Competition shooters want minimal recoil and the current trend shows shooters that compete with lighter polymer guns lean towards heavier bullets, while those shooting heavy race guns favor lighter bullets. In general, you may find that your gun performs with better accuracy with a certain bullet w. eight. Find out how to load the 9x23 Winchester. I did this to take advantage of the reduced recoil. Your sights will lift less at the same power factor with a heavy bullet vs. a lighter bullet. In 30-06 Springfield, Winchester’s 150-grain Ballistic Silvertip drops 7.3 inches at 300 yards (with a 200-yard zero.) If you calculate the recoil force, you'll find that all bullet weights produce the same recoil when loaded to the same power factor. You may find a lighter bullet has performed consistently better than a heavy bullet in a ballistic testing (or vice versa); because of all the factors involved, relying solely on bullet weight is unrealistic. The 6.5mm Grendel is just such a cartridge. Bullet grain plays a significant role in the performance of a bullet. No. It is calculated by multiplying the bullet weight by the velocity, then dividing by 1,000. a 122 grain has less recoil than a 154 grain while fired from my SKS rifle. make perfect sense for plinking. For more detailed, 1 grain is equal to 1/7000th of a pound. Picking out a round for hunting follows the same line of thinking as picking out a round for self defense – you want to stop (in this case, kill) your living target. Power factor is calculated by the formula: bullet weight times velocity divided by 1000. Even if the Rainier bullet data was excluded, the two Berry's bullets (230- and 185-grain) illustrate the point very well. I tried to control for this by using the same type of bullet (plated), albeit two different brands. Any suggestions would be appreciated. There isn’t always any predictability to what that might be, so if you’re looking for maximum accuracy out of your gun, you’ll need to try a wide variety. While this isn’t always dependent on weight, it’s one factor that can affect the shape – also known as the profile – of the bullet. 165-grain vs 180-grain .40 S&W ammo? Self-Defense & Competition Shooting Tips. How the shooter feels the recoil, though, is totally subjective, so even though a heavier round may technically generate recoil, it’s still a matter of how you personally perceive the blast. RN 1000rds Reman, PRICE $201.04 from 9MM LUGER Instead, we have to understand the relationship between bullet weight and recoil. The Action Pistol’s 205-grain bullet produced a noticeably softer recoil impulse. Either way, if you find that you don’t like how your gun feels when you shoot it, changing bullet weights can be an easy way to adjust that. Created around a 250 grain bullet, the standard 450 Hornady ammunition can knock a round at 2,200 FPS despite its much lesser size. The exact Force is difficult to calculate, but generally Force = Mass * acceleration. 300 Ultra Mag vs 300 Win Mag. Bullet weight vs. Recoil Thread starter TonyDedo; Start date Feb 2, 2014; TonyDedo. Selecting a caliber that is adequate for the game and conditions you are hunting in will be more important than any particular bullet weight. The pistol was virtually recoiling too much and hurting my hand. A common distinction is between "Minor" and "Major" power factor, and it determines the score value of peripheral hits. To learn more about power factor. Third, there is the issue of recoil impulse. Joined: Mar 16, 2006 Messages: 3,931. The Ransom Rest results (Figure 3) show that the 200-grain bullet had 5.9-percent less movement, and the 230-grain bullet had 9.1-percent less movement compared to the 185-grain bullet. Linear regression was also used to calculate the distance the gun moved for 165 power factor. Shooters who just want to plink at the range can usually find an affordable round that consistently makes both their gun and wallet happy. We know it requires more energy to move a heavier bullet than a lighter bullet, right? The first method measured how far the gun moved in a Ransom Rest. Do these different bullet weights achieve the same power factor when loaded with the same gunpowder charge weight? If you’re choosing a self defense round, bullet weight should not be your initial concern. For whatever reason, I’ve only shot 180 grain in this caliber. For example, using common bullet weights in the .45 ACP with the goal of a 165 power factor: a 230-grain bullet at 718 feet-per-second (fps) has the same recoil as a 200-grain bullet at 825 fps or a 185-grain bullet at 892 fps (Table 1). The numbers to compare are in bold. With all these variables, it’s near impossible to definitively say which bullet weight has the most effect on recoil. It depends on the shooter. The 185-grain bullet produced the most recoil, and the 230-grain bullet produced the least. Never-the-less, the table below should give a reasonably accurate comparison of the recoil of most popular rifle cartridges. When loaded with a 108-grain bullet, the projectile breaks at a muzzle velocity of 2700fps. Heavy bullets are less affected by wind and other external conditions. Chamber pressure is going to be higher. Ten rounds were fired with each load. Increase the gun weight by, say, 25% and the recoil goes down by 25%. As you can see, you can change quite a few things about the way your gun shoots without the hassle of making changes to your equipment. Units are not important you can ignore them. These are the weights most commonly offered by manufacturers, though you may occasionally come across a less common weight that is usually made for specialty purposes. Okay, so the first part: what you gain and lose with lighter-for-caliber bullets compared to heavy-for-caliber bullets. Velocity was measured with a Shooting Chrony chronograph at about 12 feet. I went from 115s to 147s. Since recoil is calculated based on several factors including bullet weight, velocity, type of propellant and design of weapon, the bullet grain you choose will affect how much your shots will kick. Most fast varmint-type cartridges work just fine, but there are a few that excel. The 185-grain bullet produced the most recoil, and the 230-grain bullet produced the least. Subscriber Services. If you are new to shooting though, it may not be a familiar term, so what is bullet grain? What works well in one gun may not be reliable in another, but by evaluating your needs and implementing a little bit of experimentation, you’ll be able to find the best fit for you and your gun. Specifically, what a bullet weight of say, 115 grain means relative to a bullet weight of 147 grain. The formula for ammo with the least recoil is to use heavy bullets in combination with a gunpowder than produces the least recoil. The following test will determine the optimal bullet weight(s) with the lowest possible recoil while still achieving a desired power factor. Accuracy- In general, you may find that your gun performs with better accuracy with a certain bullet weight. Physics dictates that bullet grain will play a role in recoil. Messages: 4,477 Likes Received: 8. Recoil– The big debate is whether bullet weight affects recoil. Well, the weight of the bullet affects its performance once fired, including effects on recoil and accuracy. Also, please understand that there are dozens of loads for any given bullet weight in any cartridge that will produce the same velocity, but a different amount of recoil. Heavier bullets are often described as having less felt recoil, but perhaps not enough to account for other characteristics of how the gun feels and behaves through the firing cycle. a 5/8 oz slug has less recoil than a 7/8 oz slug fired from my 20 ga shotgun. A heavier, slower bullet may have more of a “roll” or “push” by contrast. There are people who swear by a heavier bullet weight in their self defense rounds and it is true that certain brands and product lines have better track records than others. Not even close. Same powder, the 140d are more recoil, but slower vs faster isn’t what I am thinking about. Power factor requirements are determined by which division one competes in, and might be caliber specific. Mar 21, 2011 #2. Recoil Levels in 7-pound Rifles. The short answer is that it really depends. Again, you need a round powerful enough to penetrate the vital organs of your target. Considerations that need to be taken include the size and anatomy of the game, the terrain, the distance at which you are shooting, and the laws and regulations where you are hunting. The science behind long range rifle shooting is vast and confusing, but there are many precision shooters out there who can offer guidance and education on the topic. All Rights Reserved. Most likely the 110 and 125 grain bullet loads. They typically shoot whatever is cheapest and most available without any problems. As I tried loading on a more massive grain, 123 grains, the speed was reduced to 2620fps. The nice thing about both rounds is you can balance terminal performance against recoil by juggling bullet weights, rifle weight, and/or using more efficient powders which require less mass to do the same work. A heavy bullet may be less likely to be affected by external conditions such as wind, but it also may be harder to stabilize resulting in keyholing, or the bullet entering the target sideways. For instance, in casual conversation a cartridge may be referred to as a bullet. Even if you’re satisfied with what you’re getting out of your current ammo of choice, it can be worth trying others from time to time to see if you can do better with a different choice. Let us also clarify that we are discussing the merits of heavier or lighter grain weights for the same caliber, such as 115 gr vs 147 gr 9mm. To test which bullet weight gives you the edge, three or four different charge weights were prepared with each bullet weight. Mar 21, 2011 #2. A light bullet, say your 115gr WWB leaving the muzzle at 1190fps would have a recoil of 0.608 slug-ft/sec. They have less recoil because they require less gunpowder. UziLand Member. Shooting 158 grain .357 mag rounds is a wild ride, for sure. There are many shooters who have never paid any attention to bullet weight. Precision Shooting- When shooting rifles at longer distances, bullet weight becomes more important. Better penetration than a 125gr with less recoil than a "standard" 158gr .357 load. Check your reloading manual for that information. This isn’t the weight of the entire round of ammunition, but just the projectile that leaves the barrel. This begs the question from many shooters: When reloading for competition, which bullet weight gives you the edge? The 10mm Range Officer Elite firing a 180-grain bullet at … However, this slight deviation in shape that would result in a small deviation in internal volume did not adversely affect the main results. Since this year is such an anomaly (I hope), I’m going to give the overall nod in this category to the .223 Rem. To learn more about power factor, check out this post. However, stabilizing the bullet can also be challenging. For example, when fired from the exact same rifle, a .300 Win Mag load firing a 165 grain bullet has about 25% more recoil than a 7mm Rem Mag load firing a 150 grain bullet at a similar muzzle velocity. These are the weights most commonly offered by manufacturers, though you may occasionally come across a less common weight that is usually made for specialty purposes. Competition- Depending on what competition venue and division you are competing in, power factor will probably be important to you and you will need to be sure your ammo is meeting the set requirements. Joined: Jan 27, 2014 Messages: 103 Location: Northern Arizona. But they all typically have about 200 to 240 ft lbs of energy --- which by Newtons Law means that the energy out the end of the barrel is offset in the recoil. Discussion in 'Handloading and Reloading' started by UziLand, Jun 26, 2014. Bullet Weight & Recoil. 9mm bullet is 0.355" diameter. This can differ from gun to gun and experimenting with different rounds is the best way to figure out what works best for you. Recoil is generated as force is applied. This was confirmed by both methods of measuring recoil. So the figures in any recoil table should be taken as approximate. Many of these sports are timed events, and a light recoiling load can allow faster follow-up shots, giving the shooter a speed advantage. Its recoil is sufficient to flip the muzzle a good 30 degrees when even an experienced shooter fires it. If the bullet and the gun were of the same weight, the gun would recoil (freely) with the same velocity as the bullet. Apparently recoil hasn’t made its way to Hollywood and that part of the West Coast yet. For those using the metric, 1 grain is equal to 15.41gram. Unfortunately, there are no particular rules of thumb as to what will hit higher or lower. Does 115gr 9mm have more or less felt recoil than 147gr? Lighter bullets must travel faster than heavier bullets to reach the same power factor and therefore require more gunpowder. Because heavy bullets generally travel at a slower velocity and don’t rotate as fast, they can be harder to stabilize than a lighter, faster moving bullet. Light bullets tend to have a quicker "snappy" feel while the heavy bullets tend to have a slower "pushy" feel. Bullet penetration and expansion are far more important than weight when selecting a round that will be used on targets other than paper and steel. The 150-grain load penetrated 6¾ inches of gel while the 100-grain load penetrated 6½ inches. The Federal Premium Low Recoil 85 grain Hydra Shoes make a very nice carry load. In comparison, for the .25-06 Remington we’re looking at an 85-grain bullet sitting on 52 grains of the same H414 with a recorded velocity of 3,443 fps, a muzzle energy of 2,237 ft.lbs., a recoil impulse of 2.45 lbs.sec. To document this, I tallied the .30-06 hunting loads listed on the MidwayUSA website, finding 31 with 150 grain bullets, 32 with 165 grain bullets and 41 using 180 grain bullets. Too bad. Power factor requirements theoretically put all ammunition on even ground with respect to recoil. Recoil for different bullet weights in the .45 ACP was tested using Winchester 231 gunpowder. A half-century in the making, the new DGX Bonded is Hornady's best-ever dangerous-game bullet. Thread Status: Not open for further replies. For a backpack .357 mag I would look at Buffalo Bores 140gr .357 Short barrel load with the Barnes bullet. 45-70 is slow recoil. Specifically, i show how the Wii remote controller is positioned using the wrj4P5 drivers. 1SOW, Jan 12, 2011 #8. The same amount of gunpowder produced similar velocity regardless of bullet weight (Table 2), though the heavier bullet usually went faster with the same charge weight. You’ll need to buy a box or two of ammo in different bullet weights, then shoot the best groups you can at different distances to see what works best. 147's loaded with fast burning powders have less recoil than 124's loaded with slow burning powders. By changing the height of a sight, you can make them match the sight picture you’d like to see (your point of aim) for the hole you make on your target (your point of impact). The original load, a lead round-nose 158-grain bullet, was marginal as a stopper. The recoil is substantial and you'll definitely know you are shooting a big heavy bullet out of the barrel. Gentlemen and fellow addicts . 7mm Rem. Lbs.) As we know, every fraction of a second can determine who wins the match. It’s not unusual to be limited to doing no more than hammering the rear sight to one side or the other to shift your hits left or right. I read somewhere the … Light bullets must go faster than heavy bullets to achieve the same power factor, so they accelerate faster and spend less time in the barrel. Muzzle loader is slow recoil. That’s not a huge difference, but that will increase with range. © 2015-2021 TargetBarn, LLC. For all things ballistics, reloading and ammunition related, turn to. The higher the force requirement to accelerate the bullet to a given velocity, the greater the recoil. Other factors that can alter perceived recoil include barrel length, gun weight and design, and the shooter’s grip and stance. Here we will look at the relationship between bullet weight and recoil. for my 38/357 Mag., etc.). When you see “grain” (sometimes abbreviated as “gr.” or “grs.”) preceded by a number on a box of ammo, it is referencing the weight of the bullet. This article basically contains two parts. This means that the lighter bullet will spend less time in the barrel than the slower moving heavy bullet, causing a difference in perceived recoil. Power Factor & Recoil: Which Bullet Weight Gives You the Edge? The two Berry's bullets have virtually identical nose shapes, so their difference in internal volume is ideal for this test when they are loaded to the same COL. As bullet grain affects the speed of the round going down the barrel (heavier bullets are harder to move) the designed rifling can have less of an effect on a bullet moving too fast if it is too light. I personally found for myself that running any bullet faster than 1,200fps had pretty unpleasant recoil and long shot recovery times. There are people who swear by a heavier bullet weight in their self defense rounds and it is true that certain brands and product lines have better track records than others. Bullet Weight vs. Recoil: A lot of people intuitively believe there must be some link between bullet weight and recoil. Your barrel length and twist rate will play a part in your ammo selection, with heavier bullets requiring a faster twist rate. Many organized shooting sports require ammunition to achieve a minimum power level to qualify and be scored in a specific division. They typically shoot whatever is cheapest and most available without any problems. Typically, recoil is less snappy with heavier bullets. Other factors that can alter perceived recoil include barrel length, gun weight and design, and the shooter’s grip and stance. Competition shooters want minimal recoil and the current trend shows shooters that compete with lighter polymer guns lean towards heavier bullets, while those shooting heavy race guns favor lighter bullets. You see, it matters how much gunpowder is required to achieve the necessary velocity, because gunpowder weight affects recoil force. The grain is a unit of weight measurement and is defined as being equal to 0.0648 grams. Some guns, pistol and rifle, just “like” certain bullet weights or even certain specific ammunition types, better than others. Lighter bullets traveling faster usually feel “snappier,” for instance. 77 3 0. So if they're presumably running the same energy to ensure function (not necessarily the same speed) to ensure pistol function the heavier slow bullet recoils more mildly, perhaps it's recoil velocity, more below. At 500 yards the lighter bullet shoots 3-inches flatter, maybe the difference between hit and miss. Ultimately, find a cartridge that performs well under testing or real world applications and most importantly, one that functions well in your gun. Reloading tools are a lot like kitchen appliances; there are a lot that make life easier, but only a few that are absolutely necessary. COL is another variable that can affect these results since it affects pressure, which affects velocity. These cheap postwar variants offer perhaps the best value on the vintage-Mauser market. A heavier bullet will not always have more recoil than a lighter bullet, as many factors come in to play. We know that is 147 grains, or 0.021 Lb. When Bullet Tooth Tony fires that massive handgun, his hands hardly move. The longer bullet will take up more case and raise the chamber pressure. The .300 Blackout is here to stay, and we take some time to look at new technology surrounding this cartridge. If we look at IPSC, for example, there is a requirement for a minimum PF of 125 for divisions shooting minor.
