HST micros where designed for barrels under 4" for better expansion. Maybe a dumb question; In an attempt to improve accuracy for my next range trip I might shoot 124 Grain 9mm vs. 115 Grain. Shooting 115GRN and 147GRN 9mm. bigger bullets cost more and generally use less powder - but the cost of the bullets is more than the powder saved. If you want a 147 gr 9mm bullet to be travelling the same speed as a 115 gr, the pressure will probably be in the +p range. Looking at commercially available loads, most standard 147 gr loads are running at 1000 fps or lower. I shoot a lot of 147gr and find that both the noise and recoil are less than that of the 115gr and 124gr in my XDm 9mm Comp. Then I tried 124/5s and decided I liked them better. Can someone please help with authenticity. On the lighter end of the bullet weight spectrum, 9mm 115 grain bullets have a slightly higher velocity than heavier projectiles and are a … Whether a person will feel the difference depends on the person the, the weapon etc. Different people end up preferring different things (maybe their gun runs better on lighter bullets, or the cost difference matters to them, or whatever), but it is definitely worth experimenting with heavier bullets (at the same PF) to see if you enjoy them and/or see a benefit in your shooting. The gasses generated by the burning powder have mass. All Palmetto Reloading Gear/Accessories! For .45 ACP I have been shooting 185gr Hornday XTP but now I have 200gr Ranier plated HP and also some 230 gr to test as well. In other words, for heavy and light bullets both meeting the minimum power factor, the heavy bullet will have less muzzle energy and therefore less felt recoil. The owner suggested for my Sig P290RS and Beretta Nano 19 that I use standard pressure 147 gr loads. A 9mm bullet weighing exactly 124 grains. for you guys is as a shooter do you notice any difference in feel and recoil impulse in shooting heavier bullets? Thus, when you include the jet of gas coming out of the muzzle, the lighter bullet using a larger charge of the same powder than the heavier bullet will have more total, actual recoil... separate and apart from the subjective perception of more "recoil" coming from the blast and flash. JHP and the Secret Service 115 gr. This loading breaks 1047 fps average in the GLOCK 19. As most 9mm handguns are short recoil action (as opposed to blowback) it should be possible to load 115gn bullets to recoil the same as 147 and still operate the action, although the lighter bullet will be in the barrel for a shorter time and may change the felt impulse. Lv 5 9 years ago The recoil difference between factory loaded 115 grain and 147 grain is less in the 115 grain. For a better experience, please enable JavaScript in your browser before proceeding. I have been using 147 gr in my mp 9c and beretta m9a1 with great results. This is a borderline situation and you could get by with either a 115/124/127 grain load or a 147 grain load but if you go with the 147 grain, try to find it in a +P configuration. Yeppers, all things being equal bullet weight does make a difference. It depends on what I'm shooting. The 147 gr or even better, the 150 gr. (Ball not HP). 115gr. My question is re there any disadvantages to using this ammo? I would recommend not going below 4" in barrel length for the 147gr loads since they will need enough barrel to burn all of the powder and to accelerate to enough velocity. You must log in or register to reply here. Purely subjective IMHO, but for me a 124/5 at a leisurely 1050ish was accurate, pleasant to shoot and tossed the brass nearby. In my ballistics file, I show that some of the 124 gr 9mm ammo has a MV of only 1050 fps, which produces only 304 ft. lbs. +P+ JHP loaded by Remington. For instance, most 9mm loads are either 115, 124, or 147 grain, but occasionally you might see a 95 grain, 110 grain, or some other oddball load. Discussion in 'Handloading and Reloading' started by TheDomFather, Jan 22, 2018. I always hate cleaning the lead out of a bore! As far as kinetic energy and penetration you'll have to look up ballistics for the specific load. Anyhow, a 115-gr projectile has a mass of 7.45 grams (0.00745 kilograms) and 1150 feet per second (ballpark velocity for 115-gr 9mm bullets) works out to 350.52 m/s. of Muzzle Energy (ME – the power rating). p=(0.00745 kg)(350.52 m/s), which equals 2.6114 kg m/s. 115 gr, Velocity 1210 fps, Energy 374 ft-lbs 124 gr, Velocity 1150 fps, Energy 364 ft-lbs 147 gr, Velocity 985 fps, Energy 317 ft-lbs The 147 grain has the lowest energy and should have the lowest recoil. bullet moving fast (around 1,150 fps) & the 45 is a 230 gr. For 9mm, my Hornady manual indicates better results using progressively slower powders as bullet weight increases. The industry standard for the 147-grain JHP seems to be 960 to 1000 fps. 9mm bullet is 0.355" diameter.

I contacted Buffalo Bore about defensive loads for CC. Example: You've probably heard people say "The 45 ACP is much more powerful than the 9mm." All depends on how much tin is in the lead bullet mixture. I used to Practice with 115 gr FMJs, but since I use 124 gr JHPs for EDC/SD, I practice with the same weight FMJs for the same price as 115 gr. This is a discussion on 115 grain vs 147 grain 9mm within the Pistols and Revolvers forums, part of the HandGuns, Pistols and Revolvers, Long Rifles, Shotguns, SKS, AK, AR category; i have signed up for the 4 day pistol at front sight in march. I usually just do the 2 day classes. Lighter = faster and heavier = slower. This method is also the only one that will capture the felt recoil reduction most shooter experience when shooting a semi-auto compared to a similar weight and caliber weapon of a manual action. Other excellent standard pressure 9mm loads are the Winchester Silvertip 115 grain (X9MMSHP), and Federal 124 grain Hydra-shok (P9HS1). 115 gr loads are running well over 1150 fps. In the FBI's infinite wisdom they had chosen the 115 gr. Both produce the same energy. Everything up to that was right. I think faster powders have a harder time getting higher velocities with heavier bullets while staying under the max pressure. The Federal HST in both their standard and +P configuration. Comparing one bullet weight, the 9mm is a 115 gr. It depends on how fast each bullet is loaded. 9mm 115 vs 147 grain? I shot 115 Gr for years because they were the cheapest. 9mm Depending on the 115 gr. A quick test of 9mm 115 grain vs 124 grain vs 147 grain ammunition , What do you carry? My buddy Augustus shooting his Beretta PX4. Forgot to add that with all things being equal (Lead and brass) it will not cause more wear. So you would not recommend using them in sub compact pistols then? This is about 8% less energy of the 115/124g rounds. The exact Force is difficult to calculate, but generally Force = Mass * acceleration. Some 124 gr 9mm ammo has a very low MV, and some MV are up there with the fast 115 gr ammo, and this is also the case for the 147 gr 9mm ammo as well. lead bullet, you may get leading problems when the velocity goes over 1,000 fps. Im shooting Ranier 115gr plated HP today with 4.4 gr of Bullseye behind it. This powder has an influence on recoil, too, beyond just its contribution to the momentum of the bullet. So a 147 grain bullet at 920 fps has the same momentum as a 115 at 1175 fps. Tell us in the comments!!! As you go up to a heavier bullet velocity usually drops as does recoil. More than the bullet itself. 9mm bullet weights range from 115 to 147 grains and velocities from 1,200 to 1,000. +P+ JHPs used conventional "old tech" JHP design and both had excellent track records. For guns that may jam with the Cor-Bon or Federal 115 grain hollow-points, the Remington 115 grain +P … And some folks like shooting the 147 even better. Feeling the difference in recoil. It’s believed by experts the heavier bullet gives bet. ME will be about 30% more so there has to be more recoil. Not quite true. 147 has the smoothest recoil, 115 feels sharper. OK, I bought some 115 grain and some 147 grain because I had never shot 147 grain and wanted to see if it was a noticeable difference in shooting the two. Buffalo Bore also offers fast-stepping 9mm loads in 115 and 124-grain weight. It's simple. +P+ JHPs, the "Illinois State Police" load which used Winchester's standard 115 gr. In reality if they are all loaded to the same power factor they all have the same total recoil impulse but because the heavier slower bullet take longer to accelerate to its final velocity it feel softer, more push and less snap.
