Heavy weight .45 acp load data?

I want to experiment with using some of my wicked 265gr cast hex-hp bullets in .45 acp. All of the data I have been able to find is for max load .45 super. I just want to make some punkin chunker loads at minimal vlocity. Maybe replicate the old .45 colt BP numbers at most.
How much can I safely reduce the loads listed below using Power Pistol? I will be using new brass for this and a 22 or 24 lb spring if I need to.



275gr Hunter's Supply cast FP Starline 45 Super Federal 150 1.24" Alliant Power Pistol 8.1gr 992fps

255gr West Coast PFP Federal 150 1.20" Alliant Power Pistol 8.5gr 1130fps



P.S. what would be the safest and strongest platform for this experiment. A Sig 220 or M&P .45

First of all the 1911 pistol was never designed to handle those bullet weight and is a low pressure pistol compared to some revolver loads. If you insist on trying those loads in a 45 ACP case, I would suggest a Ruger Convertible with the 45 Colt/45 ACP cylinders. The Ruger is a very strong revolver and should hold together for a very long time before you blow it up.

.45 super.....460 Roland...


Again, not trying to make high pressure hot loads, just mid velocity loads w/ heavy bullets

I heard of a conversation with Ed Brown once...

A guy was havin' a minor problem with one of his creations, and he had Ed on the phone.
Ed asked what ammunition he was using in the gun. The guy told him that it was a 200 grain SWC loaded to 950-960 fps...with Unique...chronographed.

Ed replied:

"Whoa, man! You're gonna break my gun!"

Handloader Magazine, at least according to LoadData.com, in #37 had some 45ACP heavy loads. Bullet weight was 305gr and the powders were really slow magnum pistol powders, velocity showed was in the 580fps to 650fps range.

I will have to admit, I would never use a bullet that heavy in the 45ACP, the 45 Colt, now that's another story! ;)

I regularly use a M625JM for my heavy loads. I cast a 240gr LSWC and have shoved it out of the 4" tube at 1100fps with SR4756. Got the load out of the Speer #8. You may look there, although, some folks get right testy when you mention that manual! :D

Personally, I wouldn't shoot them out of the auto platform either. No sense beating a gun to death for just to test some bullets.

Sounds like you got yourself a Miha mould! Me too, the 45-270-SAA copy with the hex and round pins. Never could get the hex pins to fill out too well, the round ones do fine though. Gotta use a lot of tin and keep the melt temperature up.

At any rate, thats my two cents worth! ;)

Sounds like it would be a heck of a good bowling pin load

Why not just buy the caliber of gun you want to have instead of trying to cram it into the gun you have?

Maybe that is the answer to the question? The Rowland is a fun handful.

Thanks Chevelle. I just loaded up some test rounds with 260 grainers with 4.5 gr of W231 (aka HP38). Hopefully, they will feed ok. That is my biggest concern...

i shot them out my SF 1911-A1, XD45, PT1911, ALL WORKED FINE

FWIW, I loaded and shot 8 cartidges with 4.5 gr of HP38/W231 to 1.270 and they fed and shot fine. These were actually 260 grain LRNFP 45 Colt bullets.

Loading up some today with a starting load of 4.5 gr and going up to 6 grains of Power Pistol. Should be interesting.
