I am trying to reduce the recoil for them a little bit. It determines how fast the bullet will travel too. The gun seemed to flip a bit more than when shooting some of the lighter bullets. Higher grain bullets are available with the Remington having in stock 77 grain âOTM rounds that are typically used for military marksmen. The .40 definitely has more kick to it, with bullets ranging in weight from 155 to 165 or 180 grams. .325 WSM - 37.5 ft. lbs. but the .270 part will ... A 150gr bullet has a higher ballistic coefficient and will carry very well and retain its ... because the heavier bullet will kick more. Therefore, it's not possible for a 180 grain bullet to generate more recoil than a 240 grain bullet unless the 180 was loaded to multiple velocity factors. This with an unexpanded bullet. I also measured a reasonable and desirable .0004 pressure ring on â¦ Letâs go back to the .45 ACP example. A light grip with less muscle tension allows the pistol to kick higher, throwing the bullet higher. (BTW: the .308 military loading is a 147 grain 7.62mm bullet at 2800 fps) They designed the cartridge and called it the .276 Pedersen. On the heavy end, a 147gr bullet is the max bullet weight. These higher grain rounds do require use in a âthroatedâ barrel due to their longer overall length. I got a chance to get out and and shoot at the chronograph today. Before loading some up to try I took 10 bullets out of the bag for some quick measurements. Newton's Third Law holds that for every action there is an opposite and equal reaction. This is because larger bullets require more energy to be launched at a high speed. The 9mm bullet types are standard issue for NATO countries and law enforcement officials around the globe. +1-The lighter bullet load has a higher recoil velocity, which "feels" like a harder kick, since it comes back at the shooter quicker. Caliber remaining the same, the cross sectional density will increase with weight. They have been shooting a 50 grain off of a shooting sled, and it still has some kick. In a .357 comparing 110 to 158 or 180 grain bullets you would be able to tell the difference too. Thus, two things add to the lighter bullets velocity. Does the grain market, like heroic Brock, have a bullet through its chest? from a 6" barrel. A 9mm round typically stores only four to six grains of propellant. Remember also that bullet construction can offset some loss in mass. Oct 19, 2019 #37 J. The pistol does not overly challenge a novice nor limit an expert. Also, some cartridges burn power more quickly than others, and therefore the recoil impulse is quicker, resulting in higher perceived recoil despite its numbers on paper. 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. (180 grain bullet at 3300 fps; 9.75 pound rifle) In addition to these long range magnums, most hunters would be well advised to avoid certain big bore "woods" cartridges, especially in â¦ I saw that you can buy the pellets in 30 or 50 grain. of H110 with a CCI 350 primer and a 350 gr. This would give us the same total recoil impulse as calculated above. 27.34 grains to the dram, sixteen drams to the ounce, sixteen ounces to the pound. High speed and massive tissue damage and energy dump. In most cases, the larger the bullet you have, the slower the velocity. Unless something, heavy wool coat for example, opens up that bullet too soon. Now if we loaded a 147gr 9mm bullet to have the same total recoil impulse of the 115 gr load of 0.608slug-ft/sec we would have a 147gr bullet going about 930fps. Any suggestions would be appreciated. My personal test pistol exhibited a velocity of 1,050 fps with the 185-grain Gold Dot load and 1,010 fps with the 200-grain load. If the 130's group well in your gun, I sure wouldn't mess with it! Interesting ---- With my 44 Special handloads, I've loaded 200 grain and 250 grain bullets to the same velocity (within a few FPS) and the heavy bullet STILL hits about 3" higher @ 25 yards. of each other, with one bullet .3 gr. First, letâs start without including the gunpowder weight. Larger Bullet (in Same Cartridge) Generally Means Slower Velocity. 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 heavier bullet actually takes more effort on the part of the expanding gasses to get it moving down the bbl. Oct 17, 2012 Opinion Cycling through the absurdities of the hog and cattle cycles without falling off It should go without saying, but we will say it anyway: another crucial factor is the firmness of the shooter's grip. Two, you can use more powder and that pushes the bullet even faster. My goal is to get back on target as fast as possible while shooting timed qualifiers. ... but retain V in a more efficient manner than a lighter bullet with a lessor ballistic ... A boyhood friend shot a 222 Rem 50 gr bullet and never lost an animal. Primers all look good. Usually, lighter bullets will have higher velocities than heavier bullets of the same caliber. If you have an idea of the typical range of bullet weights for the caliber, then you can tell whether any given load falls more toward the heavy end or lighter end of the spectrum. Thanks for any input. I am thinking of stocking up 1000 rounds free shipping on 9mm 124GR. and 223 Rem. Where lead-free bullets must be used, the 35-grain Ballistic Silvertip LF in 22-250 Rem. bullets give ya. The lighter bullet will loose velocity faster than the heavy bullet. So a higher grain can be louder, and also have more recoil/kick than a lower grain You have a 230-grain bullet and 6 grains of powder. Does 115gr 9mm have more or less felt recoil than 147gr? Since getting a lighter bullet moving creates less pressure, you can use more powder. I have seen 230 gr JHP .45 bullets. One, it is lighter and given the same amount of powder, it is going to be faster. Letâs do the math. The powder charge does not make the difference in kick the heavier bullet does. The grain is the weight, just make sure you note, the higher the grain-the higher the weight of the bullet and most likely higher amount of powder. just wondering if yall thought one might need a little more power than what the 130 gr. Classic 9mms have the same bullet sizes as the bullets in the .380 and .38 Special. Handgun Weight. This means that hunters are able to control the firearm much better, making more accurate and effective shots. Hornady XTP, I was getting an average of 1253 fps. But that is more than offset by the higher capacity and lower recoil (allowing more shots on target) that a smaller bullet (like a 9mm) will generally have. A firm grip with more muscle tension reduces muzzle flip and therefore the point of bullet impact. A 230-grain bullet exiting at 850 fps in a 2.5-pound gun produces 4.85 ft-lbs of recoil. I don't care for them, as the 185 load actually has more energy than the 230 does â¦ Weights of 9 of the 10 were within .1 gr. RN 1000rds Reman, PRICE $201.04 from 9MM LUGER .45 ACP normal JHP loads are 185 grain, while normal FMJ are 230 grain. Therefore the gasses are pushing back on the gun harder than they do with a lighter bullet. heavier â nice! Bullets do not follow a laser beam-like, perfectly straight line to the target, nor does the nose of the bullet always point exactly at the point of aim. The heavier bullet will kick you harder than a light bullet will. There is some argument to be made that a wider bullet (like a .45) does more damage, as it creates a slightly larger permanent wound cavity. However, some 223 bullet weight can go up to 80 grains. Multiple forces are in effect that may cause the bullet to yaw (rotate side to side around its axis), tilt nose â¦ A super light bullet at very high velocity may not penetrate deeply enough to damage vital organs. Also, at higher velocities, the bullet is able to realize a flatter trajectory meaning longer shots are possible. (220 grain bullet at 2840 fps; 7.5 pound rifle) .30-378 Weatherby Magnum - 42.6 ft. lbs. JHP .357 Magnum bullets are lightly constructed. The pistol was virtually recoiling too much and hurting my hand. Ogives of all ten were well within .001 of each other â nice! are perfect. A grain is the smallest unit of measure in the avoirdupois system. At given ranges the heavier bullet will have more Kinetic Energy than a light bullet. Check out cutting edge bullets and look at their raptor line of bullets. 9mm normal JHP loads are 115 grain, while FMJ are 125 grain. The heavier a handgun is, the more recoil energy it will absorb. Thatâs not much in relation to its 115, 124, or 147 grain bullet, but it still has mass. Would someone enlighten me on felt recoil/vs grain of bullet. The military decided it should be between 6.5mm & 7mm in diameter, and should weigh no more than 120-130 grains. Lower grain will travel faster when shot but also has less weight pressure (knock down power) and a higher grain will not travel as fast but is has more weight pressure. Generally speaking, lighter bullets (lower grain weight) are loaded to higher velocity. While the cartridge produces around 1200 ft/lbs of energy, which is more than a .44 Magnum, it also has less recoil. I agree that you are perceiving a more violent recoil, perhaps due to muzzle flash or report. Mathematically calculated recoil force of three different bullet weights at the same 165 power factor based on actual gunpowder charge weights. The grain is the weight of the bullet. Lighter bullets can be propelled by a larger powder charge. Does anyone know if 30 grains of triple 7 pellets would be enough power to kill a deer inside 50 yards with a 50 cal muzzleloader? In theory, for a 9mm pistol the lightest bullet that will operate a slide is about 106 gr, however in practical application, a 115 gr is much more reliable. These bullets weigh anywhere from 115 to 147 grains. I like to go with a middle of the road grain. 9mm. Therefore, we have to account for it. For example, American Eagle makes 9mm full-metal jacket rounds with 115-grain bullets and 147-grain bullets. As I said, there are exceptions to this. I've had people (that should know) tell me that slow motion videos show conclusively that the bullet is out of the barrel before recoil happens. It fired a 125gr 7mm bullet at roughly 2700fps. In a .45, if you compare 165 grain with 230 grain loads you would feel the difference. The effective ballistics of the .45 GAP involve a 185-grain or 200-grain bullet at about 1,000 feet per second (fps). If we use the 1.5 value for the gunpowder, its new weight value is now 9 grains. Light, fast hollow points tend to expand more rapidly and penetrate less. The light 125 gr. If two loads are equal in energy, the high velocity lightweight bullets will have less recoil than slow heavy bullets. Using 19.0 gr. As defensive bullets, they offer extreme stopping power when used against people. The lighter the gun, the more the kick with all else being equal. More powder is necessary when the bullet is heavier due to the larger mass needing to be moved. As lighter bullets are used, slide thrust decreases and as heavier bullets are used, velocity drops below acceptable limits. A 9mm bullet weighing exactly 124 grains. But the .50 tends to flip a lot anyway.
