    45 Super?

    Hey guys,

    I got into a discussion with a guy today and he said that the 9mm has basically been suped up since it was originally introduced, but the 45 acp has remained virtually unchanged. He than started mentioning 45 Super and how it can be run in a normal 1911 with no damage to the gun whatsoever. Never heard of this caliber before, have you?

    Yep been around for a while. Some 1911 can handle it, some can't. They at the very least need a spring change. Also I believe there are or were spring kits for HK USP 45 to 45 super.

    I wouldn't recommend just shooting 45 super in any 1911. Older guns, cheaper cast guns may not hold up long unless you want to shoot just one round

    A 230 FMJ at 1100 fps isn’t enjoyable out of a 1911.

    Your rate of fire, shot to shot, goes out the window with recovery time from recoil.
    It’s a better hunting than a defensive handgun in my book.
    That said, the sectional density of a 230 gr. FMJ is lousy in comparison to the heavier .45 Colt or .44 Mag bullets available in a revolver.
    A steady diet of the cartridge will accelerate wear to pistol, in spite of heavier springs.

    There’s a reason it was never a popular cartridge.

    There’s also the .460 Rowland which seems to be a little more popular as a hunting cartridge. Brownells sells conversion kits for 1911’s and Glock 20/21’s. I’ve always thought a S&W 625 conversion would be cool, but still not as effective as 44 Magnum or 45 Colt revolver in the end.

    There's also the .450 SMC, a variation on the Super that uses a rifle primer and thicker brass.

    I've long wondered what a full-power 10mm-rated (as opposed to the Minus-P of the old FBI load and current industry standard) frame, up-bored to .45 Super/.450 SMC and pushing a 255- to 260-grain .45 Long Colt JHP like a Gold Dot at ~38,000 PSI could do for Terminal Ballistics... especially out of a PCC like a Thompson.

    ^ This would be a thumper, like a +P .45 Colt, a fine woods/brush gun.

    I am running a 20lb flat wire recoil spring, 34lb mainspring, and Harrison flat bottom firing pin stop. Empties are landing 8-12 feet away at approximately the 4 o'clock position (same as 230gr in factory configuration). My estimation of where empties land is where I collect them so that is after a bounce or roll on concrete on an open outdoor range. Another thing to check is your barrel lug engagement if you are going to really run it hot. My 45 super load is an Extreme Bullets 230gr FN coated bullet over 10.4gr of Alliant Power Pistol with CCI large pistol primers and Starline 45 Super brass. I also run a load using pulled 230gr HST's 10.2gr of Alliant Power Pistol with CCI large pistol primers and Starline 45 Super brass. Chrono is averaging around 1230fps. I had run my powder load up to 10.8gr, but started seeing the primers getting flat and a more pronounce tear drop shaped firing pin impact than I like to see. The video below if from a local indoor range.

    Is there any truth in H&K pistols being rated for 45 Super?
    I have a USP-C and if it's G2G...?
