what style bullet would you use

"I would question pressures from a 45 acp load pushing 260-280 grn bullets 1300 fps though. Standard hardball was 230 grn bullet around 850 fps."

The velocities xdmalder quotes are quite realistic and obtainable. My 45 ACP rifle has a 16 1/4" barrel. Velocities in that barrel gain considerably over the same loads in 5" barreled M1911s. I gain 100 - 200 fps with commercial and US milsurp hardball. A gain of 225 - 270 fps is made with 7.5 gr of Unique under 185 - 200 gr jacketed or cast bullets. Those run 1240 - 1310 fps out of the rifle. All of those loads have been pressure tested by me and run under ANSI/SAAMI +P 45 ACP MAPs.

My standard "heavy" load for my S&W revolver is the GC'd 452490 at 245 gr over 7.3 gr of Unique for 1210 fps out of the rifle. I have 2 other loads in development with that bullet using Bluedot and LilGun that are pushing over 1400 fps out of the rifle. I have not completed the testing of those as of yet.

Gotta say that is one sweet looking rifle! Is it using 1911 mags?

[Larry Gibson]

It certainly does use M1911 mags

Well so far I started with accuracy loads of around 1200 fps and the most accurate load were at around 1300 fps. They were printing around 1" at 50 yards. I like that accuracy for a 100 yard rifle so now I will start to work down tomorrow to a 1100 fps load to see what kind of accuracy develops.

I just have to say your rifle is very desirable. Would love to have a similar one. For me a solid WFP cast of 60 / 40% WW to pure lead, pushed as fast as accuracy would allow would be my goal. Chances are many variations would work, and even may work well, but a big meplat helps in straight tracking within the target animal and thus helps in shot placement throughout the kill zone.
