By contrast, our average handload for the .25-06 Remington uses a 100-grain bullet on top of 52.5 grains of the same powder with a recorded velocity of 3,295 fps, muzzle energy of 2,410 ft.lbs., a recoil impulse of 2.63 lbs.sec. Lighter bullets must travel faster than heavier bullets to reach the same power factor and therefore require more gunpowder. For most plinking at the range, not a whole lot. All were loaded to the same 1.240-inch cartridge overall length (COL). Features such as the no-clog hollow point bullet and a design and powder load specifically for use in a full size handgun contributed to the decision as well as consistent performance in testing. Sometimes you find a cartridge that really shines when it's handloaded, and it reinforces the notion that reloaders can improve the performance of their chosen cartridge and firearm. A common distinction is between "Minor" and "Major" power factor, and it determines the score value of peripheral hits. So now we know that there are different weights for bullets and that this is measured in grains, but what does it mean for the shooter? (If your curious 4.44x10^-6 slugs per grain. Joined Jan 31, 2007 Messages 3,636 Likes 425. The .223 Rem. The .45 ACP TRP firing a 230-grain bullet at 880 feet per second generates 5.43 foot-pounds of energy. The grain of a bullet is simply its weight. Some guns just don’t like certain cartridges and you want to know what your gun likes before you need to use it. For more detailed, 1 grain is equal to 1/7000th of a pound. Does it make a difference if you're carrying 9mm 147-grain or 115-grain? As you shoot those groups to see how high or low they impact compared to your preferred sight picture, you may notice that all else being equal, ammunition with different bullet weights might feel different in your hands. Different bullet weights produce different amounts of recoil when loaded to the same power factor. Units are not important you can ignore them. Exploring several reasons why it makes sense to reload 7.62x54R for Mosin Nagants. What I'm saying is that if you loaded a: 95 grain 9mm bullet with .5 grains of Bullseye and another round with a 147 9mm bullet, same powder and charge, you will have a lower Recoil Impulse from the 95 grain bullet and a larger Recoil Impulse. A grain is a unit of measurement of mass. No. You see, it matters how much gunpowder is required to achieve the necessary velocity, because gunpowder weight affects recoil force. Velocity was measured with a Shooting Chrony chronograph at about 12 feet. Since the point is to stop a threat, you want ammo that travels deep enough into the target to hit vital organs while expanding enough to not leave the body and cause collateral damage. 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. so I would conclude that a heavier bullet produces more recoil. In 30-06 Springfield, Winchester’s 150-grain Ballistic Silvertip drops 7.3 inches at 300 yards (with a 200-yard zero.) The .300 Ultra Mag can fire the same weight bullet approximately 200-300fps faster than the .300 Win Mag. Find out how to load the 9x23 Winchester. All Rights Reserved. Which gunpowder does that? 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. The Future Of Special Operations Small Arms. Recoil is straight backward. Velocity, energy, and even the burn rate of the specific powder used can contribute to differences in felt recoil. 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. I would go 300 win mag, because I plain like 30 cals. Using heavier bullets solves the problem, but I have also found that there is a limit to the advantage of a heavier bullet. 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. I'm assuming either bullet will bring down any whitetail at reasonable ranges, and I'm inclined to go with the 120 grain, guessing it will be lower recoil than the 140 grain. Although Remington could have a greater advantage for accuracy, bullet selection, accessible ammunition, and big game hunting, we could also name Creedmoor’s exceptional benefits. 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. Its 180-grain Ballistic Silvertip drops 7.9. Two different rounds could have different bullet weights and different velocities, but equal the same power factor. This is known as power factor. Instead, we have to understand the relationship between bullet weight and recoil. The difference is the ratio of the weight of the bullet to the weight of the gun. The 150-grain load penetrated 6¾ inches of gel while the 100-grain load penetrated 6½ inches. Bullet grain plays a significant role in the performance of a bullet. Two different rounds could have different bullet weights and different velocities, but equal the same power factor. 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. Since the point is to stop a threat, you want ammo that travels deep enough into the target to hit vital organs while expanding enough to not leave the body and cause collateral damage. Many of these sports are timed events, and a light recoiling load can allow faster follow-up shots, giving the shooter a speed advantage. 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. To get started, click the link below to visit mymagnow.com and learn how to access your digital magazine. Does 115gr 9mm have more or less felt recoil than 147gr? 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. 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. I tried to control for this by using the same type of bullet (plated), albeit two different brands. The first section is an explanation of what bullet weight is. Heavy bullets are less affected by wind and other external conditions. My experience has been with 175 gr 45 swcs and 155gr .40 swcs. Unfortunately, there are no particular rules of thumb as to what will hit higher or lower. Linear regression was also used to calculate the distance the gun moved for 165 power factor. For instance, in casual conversation a cartridge may be referred to as a bullet. When shooting rifles at longer distances, bullet weight becomes more important. Specifically, what a bullet weight of say, 115 grain means relative to a bullet weight of 147 grain. Many handgun competitions require a minimum specification for ammunition, usually referred to as Power Factor (PF) PF = bullet weight in grains X velocity in FPS /1000. Muzzle loader is slow recoil. Which one is better? That;'s the beauty of the 327. 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. Go shopping, shooting, and experiment! The 10mm Range Officer Elite firing a 180-grain bullet at … Self-Defense & Competition Shooting Tips. Reply. for my 38/357 Mag., etc.). Would there be a decided difference in recoil in 300 grain bullets clocking roughly 2500 fps vs 270 grainers clocking roughly 2700 fps? With this, you can take out any wild animal, such as deer, beyond 220 yards using your AR-15 rifle. 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. 45-70 is slow recoil. The mass is the mass of the bullet. 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. Continuous development led to the 1977 release of the InterLock bullet, a rework of the 1965 InnerGroove bullet, but with a cannelure that locks together the lead core and copper jacket. For example, you’ll find Federal American Eagle 9mm ammo in, 115 gr., 124 gr., and 147 gr. A 55-grain or 75-grain Nosler Ballistic Tip or Hornady V-Max bullet would do great work against varmints while a 100-grain Sierra Game King could take down any whitetail in North America. Other factors that can alter perceived recoil include barrel length, gun weight and design, and the shooter’s grip and stance. There are all sorts of slang terms for a round of ammunition. Do these different bullet weights achieve the same power factor when loaded with the same gunpowder charge weight? The Action Pistol’s 205-grain bullet produced a noticeably softer recoil impulse. Messages: 4,477 Likes Received: 8. A half-century in the making, the new DGX Bonded is Hornady's best-ever dangerous-game bullet. 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. Velocity is one aspect where the 458 SOCOM has a weaker performance per round. 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. A real 50 AE cartridge, on the other hand, has a substantial 300 grain bullet. Lighter bullets traveling faster usually feel “snappier,” for instance. Recoil is generated as force is applied. A common misconception is that the grain information on the box is referencing the powder found in a cartridge. 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). Here we will look at the relationship between bullet weight and recoil. I have shot a very light .270 wsm with 117 and 140 gr bullets. This can differ from gun to gun and experimenting with different rounds is the best way to figure out what works best for you. Bullet weight vs. Recoil Thread starter TonyDedo; Start date Feb 2, 2014; TonyDedo. Local gun store had some 165 in stock so I bought a couple of boxes of Blazer Brass. Third, there is the issue of recoil impulse. To test which bullet weight gives you the edge, three or four different charge weights were prepared with each bullet weight. A heavy bullet may be less likely to be affected by external conditions such as wind, b. There are specialty rounds available specifically for the game you will be hunting, such as the Winchester Super-X .308 which is designed with a 180 grain soft point bullet specifically for deer and boar hunting. Now I'm wondering about bullet choice...will we notice the difference in recoil between a 120 grain bullet, and a 140 grain bullet, such as the Nosler Ballistic Tip? Joined: Mar 6, 2009 Location: 42. 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). are perfect. This may be a silly question but i found the recoil while shooting at the range 115 grain had more recoil than a 124 grain. |
The gold standard for the M14 in NRA XTC competition is the 168 SMK, 41 grains of IMR4895 and Lake City brass. In actuality, a single round of ammunition is made up of four basic components, with the bullet being just one of those elements. Specifically, i show how the Wii remote controller is positioned using the wrj4P5 drivers. Selecting a caliber that is adequate for the game and conditions you are hunting in will be more important than any particular bullet weight. Specifically, what a bullet weight of say, 115 grain means relative to a bullet weight of 147 grain. On my Desert Eagle, it has 6" in which to accelerate the bullet. Other factors that can alter perceived recoil include barrel length, gun weight and design, and the shooter’s grip and stance. We’ll get to the latter in a minute, but first let’s get an understanding of what grain actually is. Federal’s other .40 S&W Syntech load uses a 165-grain bullet and it speeds along at 1091 fps from my S&W M&P. 77 3 0. Because there are so many factors that contribute to recoil, we can’t determine how bullet weight alone impacts it. Inexpensive FMJs like the 147-grain in 308 Win and 30-06 or the 55-grain in 223 Rem. As I tried loading on a more massive grain, 123 grains, the speed was reduced to 2620fps. If your rounds consistently hit the target higher or lower than you want, then you have two options. That means that to move a heavier slug, recoil will be increased. Bullet grain vs recoil Very general 3d visualization of accelerometer objects. For the average shooter, reading the description on a box of ammo can make it feel like you’re deciphering a secret message. 147's loaded with fast burning powders have less recoil than 124's loaded with slow burning powders. The exact Force is difficult to calculate, but generally Force = Mass * acceleration. For example, in some divisions of USPSA competition, in order for pistol ammunition to qualify for Major, it must be at least .40 caliber and achieve a 165 power factor. Never-the-less, the table below should give a reasonably accurate comparison of the recoil of most popular rifle cartridges. 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. Then the 9mm crowd seem to favor heavier 147 grain bullets over smaller 115 grain bullets regarding recoil. The test gun was a Para Ordnance P14-45 and was fired while held in a Ransom Rest (Figure 2). However, stabilizing the bullet can also be challenging. What cartridge would you choose for a dedicated predator-hunting cartridge? If you calculate the recoil force, you'll find that all bullet weights produce the same recoil when loaded to the same power factor. Big bore semiauto or a lever gun? Ultimately, find a cartridge that performs well under testing or real world applications and most importantly, one that functions well in your gun. 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. The second section of this article contains tips for using bullet weight to your advantage and how to adjust bullet weights to maximize your potential ability to remain on target. To get the “silent but deadly” effect that .300 BLK is known for, it must be fired with the heavier 220 grain bullets which travel at slower subsonic velocities. A real 50 AE cartridge, on the other hand, has a substantial 300 grain bullet. bullets. The gun is secured in the device's rocker arm, and this assembly pivots upward when the gun fires, much like a person's hands and arms move when firing a handgun. The second method of measuring recoil was mathematical and used the bullet weight, gunpowder charge weight and velocity.
