I have not loaded 250 SWC in the .45 ACP, but I have loaded it in the .45 AR with a mild charge of Universal. Very accurate. Don't know the velocity. I have seen loads listed for the .45 AR that approach mild +P loads for the .45 Colt. I don't intend to go there with the AR.

I have some BH12 250gn RNFP from MBC for my Blackhawk and have kind of wondered what they would do in the 1911 but have not gone there yet.

I shoot the NOE 454424 Lyman clone in both .45 ACP brass and .45 Auto Rim brass but do NOT shoot them in my 1911's. I don't want to batter my pistols up with a "heavy for the caliber" bullet.

On the other hand, they do yoeman's work in my two 625's. A 250 gr SWC at 900+ fps is a very effective load.

Well any thread this old deserves a reply. I loaded up some 250 gr boolits meant for my 45Colt. They ran really well through my Norinco 1911. Virtually no recoil and when the sun was behind me I could wtch the boolits run down to the target and I am not kidding.

Take Care

I have the RCBS 270SAA mold, the are advertised to be 270 gr, but are 290 in my alloy, they feed well and work just fine in my Colt .45ACP, I have installed a 24# spring and a buffer, these bullets loaded to around 900fps are very effective hunting loads.

The Handloader magazine had an article with some .45ACP loads utilizing a 300 gr, bullet over 2400. This was about 30 years ago so I do not recall the particulars, folks have put some pretty heavy bullets in the short case and have been doing it for a long time.

I get the feeling you can almost throw rocks faster if you do that. Seriously, that has to be what... around 500 fps maybe?

I can see how the .45ACP is much more efficient than the .45 Colt since it doesn't need all the extra powder to defeat case volume. I’m guessing again but that must be a compressed load of 2400 and I read that is supposed to make it ignite better when compressed to a certain point. I have thought of trying my cast 255 grain RNFP bullets in my 625 just to see what that is like but the 200 grain SWC just shoot like laser beams. I guess with a heavier spring and I have no idea if buffers even do anything but I use them also then you could get away with such a thing. But this is where I would rather just save up and buy a .45 colt Redhawk and rock and roll all I want. But if you really want to go nuts with .45 ACP in the 1911 platform then I would think this also calls for that .45 – 08 brass cut from .308 Win brass. Just a thought.

Heavy bullet load for 45 ACP

I found I could load 250 grain Lazercast 45 Colt bullets sized 452 with Alliant Unique at a charge of 4.8 grains. I shot this in a Star Firestar and it appears to be a light shooting load, cases eject half the distance they eject from standard hardball loads and the bullets hit at point of aim at twenty yards. It was also fired in a 1911 pistol and functioned well.

Old thread ...

But all I load is 250 RNFPs in mine. Mine are only used in my Blackhawks though... Not a semi-auto. Work good. I've used AA#5, Unique, Universal, Red Dot, Greent Dot so far... Need to shoot it a bit more (don't shoot .45 ACP very often), but 7.5g of AA#5 seemed to work good at the time I tested it. Around 900fps.

I do not have a chronograph, but my 255 grain loads don't feel any different than 230 grain ones. I load 255 grain RNFP bullets, cast out of wheel weights, over 4 grains of Hodgdons Clays.........Robin

i know this is a long time after the thread started, but....

the fellas at rimrock offer a 250gr for the 45acp - the same one that buffalo bore uses in their heavy 45acp offering.

i've tried them in my springfield, m25 and birdhead ruger all with pretty good accuracy.

no there isn't any data in print I could find, but i'm not loading them in search of a "near 460 rowland" experiment...

255 swc 250 gr rnfp

Either 255 gr swc from rimrock or 250 gr rnfp from oregon trails with 6 grains of IMR 800 x would be a great start. I have pushed these very hard in the past and have settled in at 6 grains where the gun runs flawlessly and accuracy is at its best. My Kimber has a 20lb spring, flat bottom firing pin retainer and 28 lb mainspring. It performs very well with these boolits using metalform mags. bets advice is to start at normal weights with traditonal powders such as 231 or Unique and branch out working with what your pistol likes best. I utilize 800 x because my 10 mm devours the stuff. I also had a considerable amount of 255s and 250s to play with. Another great bullet to try is from Missouri bullet company--the 215 gr saeco 58 style boolit. SWC profile with lighter weight. That bullet really rocks in 1911 platforms.
