I want to get a pistol caliber carbine, probably a High Point chambered in .45auto.
To get the most or the most velocity from the relativly heavy 185 to 230grain jacketed .45 Auto bullet would I load differently than I would for my 5 inch barreled 1911? Powders that I already have are... TiteGroup, Universal and Unique for my 5 inch barreled .45 auto 1911's. and Power Pistol, Blue Dot, 2400 and H110 that I use for .38Spl./.357Magnum but are available for use. I do not have a chronograph. As a control or at least something I can call a standard for comparative purposes I use Aguila 230grain FMJ factory ammo. Why Aguila? because I have a shit load of it. Any suggestions, even better specific 'load data' for handloading 185grain JHP and 230grain JHP for use in a carbine with a 16 inch barrel. I'm assuming the High Point carbine has a 16 maybe 16.5 inch barrel. Thanks For Your Time VonBarky |

Here's a good article on what velocity to expect from a longer carbine barrel:http://www.ballisticsbytheinch.com/45auto.html
You may gain a few feet per second by using a slow for caliber powder but not enough to make it worth the hassle keeping carbine and pistol rounds separated. You can expect from 100 to 150fps more velocity with using the same pistol loads in 45 ACP. The main thing is by having good sights, a longer sight radius, and a shoulder stock, you'll find you now have an accurate firearm out to 50-75 yards or more rather than at 25 yards for a pistol. Note on the site mentioned that optimum barrel length for top velocity in 45 acp is around 9-12" and velocity can slow in longer barrels. Big bore and the powder is all burnt before the bullet travels the length of the barrel. Plus you can't get enough of a "lot" slower powder into a pistol case to take advantage of the longer barrel. I shoot a couple 9mm carbines and enjoy them but I shoot the same loads that I shoot in my pistols, only more accurately. |

rg1 is spot on about using slow for caliber loads. Of the powders you have, I'd recommend you load the max length you can to fit in your magazine and use Power Pistol with magnum primers. I use H110 for my 357mag levergun but that's too slow for my 10mm or 40s&w even in a 6" barrel. I use Power Pistol with excellent results in my longslide 10mm and 45acp. My son has a 40s&w carbine with an 18" barrel and with my std power pistol handloads and 165grn bullets it's spot on at 100 yds. |
