    In handguns I favor the 115's - but the 124's shoot darned good.
    In a carbine I get MUCH better accuracy with the 147's.

      From what I’ve seen 147 grain loads usually have around 320 ft/lbs of energy, most 115 grain loads have around 400. Dont get me wrong, I carry 147 grain HSTs, but energy isn’t in the 147 grain’s favor. I like 147 grain because it shoots softer, quieter, and launches a bigger chunk of lead into a target. More lead equals greater potential for expansion, more momentum to drive deep into the target, and in the event of a failure to expand, a longer bullet does more damage tumbling.

    • @CHAOSMOVEMENT
      @CHAOSMOVEMENT 3 года назад +6

      ​@@jasonvoorhees2701 Energy transfer is what stops people, period. Penetration is nice, but I would rather have my bullets expand more and transfer more energy into my target, then over penetrate my target without expending all of it's potential energy.

    For the price (and "Every Day Plinking"), the 115 grain is great. For self defense, I always carry 124 grain "+ P" hollow points (that is, if I'm not ccw a .45 with 230 + P rounds, or a 10 mm with Barnes in it). But, that's just my "2-Cents" worth...!

  • @syn4057

    In shorter barrels the 147gr never truly reaches its stated velocity. In 4.5 to 5 inch barrels and longer, the 147gr does much better in reaching its stated velocity, with higher energy dump, better wound channels and beautiful expansion out of longer barrels; average expansion out of 4.5-5 inch barrels.
    The 115gr is better for sub compact/micro, having softer recoil, above average HP expansion in shorter barrels and generally reaching stated velocity, but has a smaller wound channel, lighter energy dumps. I’ve seen tests, out of longer barrels, where the 115gr HP’s act like FMJ’s.
    The 124gr is the one size fits all; with a tendency to reach higher than stated velocities and over penetrate in longer barrels, but reaches close to stated velocity in short barrels. 124gr has average wound channels, energy dump, and good HP expansion, in all barrel lengths.
    Velocity is what causes HP’s to penetrate and expand. 147gr HP’s do very poorly out of barrels less than 4 inches, and are not as stable in flight , from short barrels. 124gr are, over all, the better choice. They shoot well, expand well, have manageable recoil, and produce a good wound cavity, in any length barrel.

    Penetration vs Expansion & Energy Transfer @Jonah Patton although unpopular, your opinion is statistically and strategically accurate. While expansion and energy transfer should be valued, penetration is the most disabling measure of a cartridge. There's a reason that military cartridges have trended smaller while their load has become bigger. On top of that, favoring a penetration round mutes your adversaries use of some walls and increases your rounds ability to get thru thick clothing and some "bullet proofing" materials. The only time penetration should not be your priority is when collateral damage is a likely issue (home defense with kids in the next room etc)

    I was just curious, what Gauge or MM thickness was the sheetmetal? I have read that here in the US the FBI testing is done with 18 gauge 3" apart, 2 sheets IFIRC. (It is to simulate a car door) This is 1 of 5 or 6 barrier penetration tests they use to evaluate their hollow-point carry ammo. 9mm 124gr now is as good as 40 cal ammo in every category! Thanks to Hornady's "Critical Duty" Ammo That is amazing. This has been proven from their testing, and shown in the data. Solid FMJ's should have even better penetration than hollowpoints. Hollowpoint ammo is designed for making massive wound cavities. Solid FMJ's are not. They are for target practice, (in general terms I am speaking about here.) Solid FMJs go straight thru a target with near zero expansion and small wound channels. That is why it takes multiple shots of FMJ's to equal the damage done by 1 or 2 shots of a quality hollowpoint ammo fired at the correct speed.

    Interesting, considering other videos showed flat tip going farther in gel

    I think I'd try this with proper support under the full length of the bottom edge of the plates, there could be some flex in play, at the outer edges where there's no support, that might skew the results. Just an observation. interesting test, thanks for doing it!

      Jay Lee 👍 off camera i stayed shooting more rounds and the results were the same. The 115gr almost always penetrates a little bit more than the 124gr.

    IM surprised that the bullet hole remained as a circle. 😮

    I'll stick with my 115 grain all day. Cheaper, more availability, and it does the job it's meant to do... Stop bad guys

    odd findings for me. i watched another video where a flat nose 115 gr bullet, in ballistic gel, went through 2 entire 16 inch blocks, while the 115 gr round nose fmj barely made it through one

    How do you all like civil defense 50 grain rounds? 2000 fps 450 energy... Pierces level 3 armor. Seems like a crazy versatile carry round

    I like 115 grain 4 my 9mm just in case the 🎯 has armor on 😉

    124 grain +P ammo is my go to. If you test +P loads it will definitely go through 2 more of those steel sheet metal.

      Thanks Gerard! ⚙ 115gr Penetrates deeper but occasionally 124gr wins (both are the same).

    Once again, 147 gr comes through. Not over penetration. No collateral damage. 147gr JHP. MY H&K will not cycle on 115gr. And really loves the 147's. When I carry the H&K, it's always 147's.

      youre just favoring something as trivial as a bullet grain because your hk was designed like garbage. get a glock 19, and itll literally eat through almost ANY brand and grain of ammo you put in it because its not designed like shit.
