If she is getting an airweight revolver, its going to have a lot of recoil regardless. How do you think about the answers? Or use a hotter 115. Mar 21, 2011 #2. 147 vs 124 vs 135 147 vs 124 vs 135. (124 gr vs 147 gr.) In fact I shoot them side by side all the time because the 115 is cheaper and more available so I practice with that, and shoot matches with the 147. The heavies tend to have a slower, less snappy but more backwards force recoil, wheres lighter bullets tend to be a little bit more "snappier." NATO spec 9mm ammo is not only 124 grains, but also holds a specific powder charge with specific velocities and ft/lbs of force. A quick test of 9mm 115 grain vs 124 grain vs 147 grain ammunition , What do you carry? The shooter didn't notice much other than a difference in sound. Report Save. Is there any? Asking about the differences between the three common grain weight of bullet in 9mm is somewhat like saying "I'm looking to buy a vehicle, what are the benefits of a 4 cylinder, 6 cylinder, or 8 cylinder engine"? +P+ JHP is what produces top results on the street in the 9mm with 92% one shot stops. We compared how 124 grain and 147 grain feel when being shot. I hunt for deals and buy in bulk so the price difference is negligible from 115s. As far as momentum goes, the extra momentum doesn't kill you any better. To my knowledge, no one has proved conclusively that 124 gr. Beyond that I just generally don’t use 115. The Advantage you gain is in the increased velocity of the 115 grain, a better temporary wound cavity and better expansion. Personally, I prefer 115 and 124 gr. Say 10-15 yards. Since most 147 grain ammo is subsonic, it would make sense to use that in a suppressed carbine. I’m a 124’er now, but carried Corbin 115’s for the longest. The only 147 grain bullets I have used that actually expanded reliably were the Winchester Black Talon line which is now called the Lawman or Ranger line. * The bigger the grain of the bullet the more the recoil.*. 147 gr hollow points always jammed in my g43. everybody told me i was a pussy basically but one guy said the OAL for a 147 grain bullet was too long for such a small gun. Putting those two equations together by replacing the FORCE in the first equation with F = ma, we get P = (m*a)/A So the pressure will vary with … If either penetrates to vitals, they'll both kill you. 9mm vs .45 ACP have different sectional densities. So with the 115's you can have rounds that just break the sound barrier at the muzzle, but quickly drop to subsonic and they encounter turbulence when they pass through the threshold - which affects accuracy. 9mm vs .45 ACP have different sectional densities. loadings fall somewhere in between. Still have questions? 0 0? 115 gr defensive loads often fall below my preferred penetration level, and those loads that do penetrate 16+ inches tend to have minimal expansion. recoils heavier. The Advantage you gain is in the increased velocity of the 115 grain, a better temporary wound cavity and better expansion. The softest shooting loads when you get into competition and making "power factor" are going to be heavier bullets, Who made the ammo is far more important than how much the bullet weighs. My preference adjust based on my needs, hence the varying grains. When buying bullets 124 grain bullet has less grains than a 147 grain bullet and therefore the 147 grain is a heaver bullet. I find that 115-grain is the most comfortable bullet to shoot with it consistently. So, I DO shoot both and the 147 clearly is a softer shooting round. I also have some critical duty 124 and 135 gr +P in the rotation. Otherwise it comes down to personal preference, some like the recoil of certain weights better. All else equal lighter is faster and has more perceived recoil. Keep in mind that if you have fixed sights they are probably going to be for 115/125 grain loadings...standard for 9mm. Plenty of ink has already been spilled in the caliber wars. Even more so when talking about the same caliber. Both guns ate this mix of loads/brands without issue. If she is getting an airweight revolver, its going to have a lot of recoil regardless. The heavier load would probably perform better if penetrating a hard surface is involved. 115gr at any pressure, and standard pressure 124/147 loads generally perform worse in all conditions according to the data I have. … 147’s are usually sub sonic which is quieter when suppressed. 147s seldom do. Grain: The weight unit used in measuring powder charges or bullet weight. 115 vs. 124 vs. 147 grain means that the bullet weight is different. It is a heavier bullet, thus travels at sub-sonic speed. Dems unveil bill for child payments up to $3,600, Chiefs owe injured girl more than 'prayers', Brady led and the Bucs followed all the way. He does some pretty good ballistics tests with different ammo. The mass of the projectile. is quieter as it doesn't have that supersonic "crack.". I would not use a 147 grain load on anything but a paper target, as it racked up 65% one shot stops. The recoil difference between factory loaded 115 grain and 147 grain is less in the 115 grain. Plenty of ink has already been spilled in the caliber wars. I currently run Critical Duty 135gr +P, in my Shield and G19's. I prefer 124gr nato for general fmj range use (the recoil is closer to actual defensive loads). I’ve never been a fan of the 147’s. Thank you! No, there isn’t. Sometimes you want light and fast some times you want heavy and slow. Thats just 2% more than FMJ ball ammo, and overpenetrates to beat the band. My question was how effective is the 147 grain vs the 124 grain in terms of defensive ammo in not only a carbine, but in a handgun as well. 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. As a general rule a higher grain weight bullet will impact higher on point of aim. I generally carry hornady critical defense rounds in mine, but have also used federal hydra shok (allegedly 'low recoil', i found no difference). Ballistics. But oh … 437.5 grains is equivalent to/= one ounce. 60,654 Posts #2 • Jun 21, 2019. The exact Force is difficult to calculate, but generally Force = Mass * acceleration. I use 147s in my full size CZ75b...but it has adjustable sights. The scandium frame is even worse, i touched off a buddy's .357 scandium frame and it was like getting hit in the hand with a sledgehammer. 3. share. A full sized steel Hi power & a sub compact polymer kahr will recoil differently. Mar 21, 2011 #2. According to smart peoples, to every action there is an equal and opposite reaction. I have a S&W 438 (bodyguard, aluminum J frame) and its has a stout recoil no matter what i use. You will find that there are 9 mm JHP loads with excellent performance using 115 grain, 124 grain, and 147 grain projectiles, as well as projectiles of other mass. bullet is heavier the a 115gr. 115 = 1145 = 150767875 124 = 1090 = 147324400 147 = 950 = 132667500 Note: All not +p loads Gold Dot Data 115* = 1210 = 168371500 124 +p = 1220 = 184561600 147 = 985 = 142623075 * Not +p The 147gr will have the least recoil energy. My goal is to get back on target as fast as possible while shooting timed qualifiers. In fact, I've shot Fiocchi 158 grain subsonics as well as it is more noticable still. Ive always shot 124 and that is what my dot is sighted for, but Ive come across some really cheap 115s and if the POI is not any different I will pick it up for practice ammo. Whats the difference in the point of impact between the 9mm 115 grain vs 124 grain. * The 115 grain has less recoil. The various 124 to 135 gr. This is the same for 115 grain, 124 grain, and 147 grain bullet. My preference adjust based on my needs, hence the varying grains. Should you count calories when trying to lose weight? For defensive loads I always go for more penetration, nowadays there’s lots of good 124-147gr defensive loads that get 16-18 inches penetration and .60-.75 inches expansion. Hot 135s, like +p, have nearly the same POI as 115/125. Lv 4. Travel slower (generally 147gr 9mm is subsonic), Drop more over distance because it's traveling slower, Require more lead on moving targets over distance because it's traveling slower, Retain more energy over distance because it has greater inertia. 461 Posts #11 • Apr 21, 2012. Bump it up to 124s. Is there a noticeable difference in recoil/muzzle flip? The range of bullet weights is actually much wider than what you might think, with the lightest being 17 grains like in a.17 HMR round and the heaviest being upward of 700 grains like for the.50 BMG cartridges. Primarily, the weight of the bullet itself. Is it really true that the worst bullet to be shot with is a 22 caliber LR.? Do not be concerned about the longevity of your investment. 437.5 grains is equivalent to/= one ounce. level 2. The mass is the mass of the bullet.
