    Hello everyone I am new to reloading and had some questions.
    I have been reloading .223 and 30-06 with great success.

    I own a Glock 17 and a Glock 21 and want to load for them.
    Here are the ammunition I want to duplicate

    Winchester ranger +P 230 and in 9mm +P+ 127

    does anyone know any data on how I can do that?

    You will want to use new brass in your Glock's if you are going to try to duplicate +P and +P+ pressures, as once fired brass from a Glock may be weakened.

    Personally I would probably not try it, but it's your choice.

    The only advice I can give is to approach those high-pressure loads with caution. Work your way to those loads and watch carefully for pressure signs.

    IMOFWIW leave the +P and +P+ to the experts at the factory. They have million dollar laboratories to ensure their ammo isn't likely to take anyone's gun apart. The 9mm is a relatively small case and pressures can rise exponentially with very small increments of powder or increases in seating depth. There are plenty of potent loads that you can find in the manuals but you will not find any +P+ listed.

    The Glock .45 doesn't have a fully supported chamber and KB's like the one shown below have been know to occure from hand loads even with once fired brass. If you want to load the .45 ACP to +P levels buy +P brass with its slightly thicker web and slightly smaller case capacity. In the .45 ACP there is a difference between standard and +P cases. Use +P data found in manuals published by reliable sources. Alliant publishes a .45 +P load on their website using only one powder and that's Power Pistol.

    What a reload load just beyond the edge can do the the Glock 21 and this shows an after market barrel that should have better case support.

    I could be wrong (not a reloader), but I doubt if anyone is even going to offer loading data for such rounds, especially a +P+ that does not have a SAAMI standard.

    New to reloading huh?

    Well, start well BELOW the highest recommended standards in your reloading manuals . . . and make sure your manuals are the latest issues. Sometimes power evolves through the years in formulations.

    Frankly, for defensive handgun loading, I ONLY load light loads so I can practice cheaper AND reduce the stress on my handguns (allowing them to last longer)!

    --For full-house, super-power loads for defense in a handgun? I ONLY use FACTORY-LOADED ammo to prevent any possible lawsuits that might be launched against me in civil court later if I have to put down a BG.

    No way would I carry handloads for self defense! In court you don't want to be accused of loading really hot stuff ahead of time so you could INTENTIONALLY inflict "more" harm or body destruction against a future victim!

    A sharp lawyer, the wrong jury, and devastating injuries due to your "custom" bullets loaded to inflict "greater" harm than "police bullets" . . . and you might be paying damages to that scumbag or his decendants . . . for the rest of your life!

    --For full-house loads in a hunting rifle round? Again, generally I don't. Most everyone who is an experienced loader will concur that the best bullet accuracy and performance RARELY, if ever, comes at maximum velocity. My .270 will shoot tiny 3/4" groups . . . at 150 yards from the bench . . . if I do my part . . . and accuracy to your exact "Point-Of-Aim" is the most important thing, both in rifle and handgun performance.


    PS: You do NOT need +P+ loads to get the job done. WELL PLACED bullets at the normal velocities will do the job just fine . . . and allow faster follow-up shots if the combat is protracted. Hard kicking loads might allow you to be shot several times YOURSELF before you can bring the barrel back down on a BG.

    PPS: I've seen a couple of Glocks blow up like this in matches. Then again . . . any handgun can get ruined by shooting ammo that's too hot.

    Slow down your bullets to the speed they are designed to run . . . and your gun will last a lot longer!
