.45acp +P looking for load data

[mikerjf]

I found this Shooting Times article interesting, about a particular Ramshot Enforcer load. I’m just a newbie loader, but seems worth a try.

45 ACP Fast Loads

According to an article by Brian Pearce in the February 2017 Handloader Magazine there are no "weak" 45 ACP's. I can't imagine how a few 185 gr. +P's would harm your revolver.
Follow the provided link and you can read the entire article.

Just taking a ride here. Maybe it´s not advisable , but will a SW 1917 revolver safely digests a VERY limited diet of a 185 grain +P .45 ACP load without ill effects?
The brand is Magtech, ( here in Brazil CBC ) and the load is a +P with a 185 grain hollow point bullet.
I just saw it for sale around here in Rio de Janeiro and want to try it, but only if it´s safe.
Don´t want to push the old gal too much.
Thanks, regards, Ray

I'm thinking the 1937 Brazilian Contract have the post '35 heat treatment. The 1946/7 Contract has lots of frames and parts from before '35.

Mine is from the 1946 batch and made in 1919. As for the cylinder I don´t know. Maybe it´s from 1919 also or post 35, I think i´ll never know for sure. Thanks Scout 308 I saved Mr Pearce´s article
Thanks to all, Regards, Ray

Pretty slow powder for a 45ACP. I've never used Ramshot for anything else so I wouldn't buy a can just to try it for this.

But when I was trying different powders for 45 Super loads I tried some 2400, an old magnum powder favorite, in some loads.

On the charts 2400 is slightly faster than Ramshot. In my loads, that were a little heavier than the listed Ramshot loads, I got poor results cycling the action.

My Colt 1911 was already setup for 45 Super loads using moderate speed powders & the slow powder didn't have the grunt for it.

I'm sure I could have made a spring change but I think powders like Power Pistol & Long Shot are better suited for (+)P loads & above in the 45ACP.

Accurate #7 might be one to play with next time though?

When my Unique loads we're making my Colt GM ring like the Church bells in Notre-Dame, I bought a bullet puller.

Using Power pistol with a Winchester 230 grain JHP projectile I have chronographed just under 1100 FPS out of a 4.25" HK USPf.

How many grains of Power pistol did you use?

I just picked up a HK USP 45, and I plan on loading some 200 grain 45 super rounds with Longshot and Power pistol.

Also thinking about picking up a 6 inch ported barrel, I want to hit 1200 fps with the 200 grain and see how the recoil is.
The USP is going to be my woods gun.

Hornady Handbook #8 shows : 45 ACP
230 grain HP-XTP
col 1.230"
Powder : Power Pistol

Starting Load - 5.5 grs. Power Pistol @ 700 fps
Maximum load - 7.1 grs. Power Pistol @ 900 fps

Start low and slowly work up to maximum load in your pistol .

Power Pistol is a good powder for max. loads in the 45 acp .

I was running 9.5 grains of PP for that load. Winchester large pistol primers, Winchester 230 JHP projectile all loaded into Starling cases

45 Super, 200gr XTP

...I plan on loading some 200 grain 45 super rounds with Longshot and Power pistol.
...I want to hit 1200 fps with the 200 grain

Back when I started working up loads in my Colt Series 70 Mk.IV 1911, prepped for 45 Super, I set 10.4gr/Power Pistol as it's max load using a HDY 200gr XTP bullet, CCI-300 primer & 1.200" COAL in S-L 45 Super cases.

FWIW, QuickLoad calculates this at 1211mv & 652me @ 26.8K psi from a 5" bbl. (Pressure drops to 25.0K psi & mv to 1190 with a 1.220" COAL.)

This was backed down from 10.8gr/P-P because the unsupported chamber's mouth would bulge cases.

I use this in my 4506 & 4586 as well even though their fully supported chambers are good for more. I like the way the S&Ws handle the recoil (feel) better than the 1911.

Work-up slow & use at your own risk.

What would you suggest for 45ACP in a new Thompson? I'd like to get a bit more velocity in +P cases.

 

[muddocktor]

What powders and bullets do you have on hand? Because all components are pretty much missing in action right now.

 

[BillBro]

I'd skip +P in .45 ACP. More pressure, slide goes faster, more gun wear for zero measurable gain. Little margin for error. Stick with John Moses Browning's specs and you can't go wrong.

Good advice. Listen.
