255 grain RNFP's for 45 acp

[MARCORVET]

Anyone ever try 255 gr rnfp's in a 45 acp? Not too heavy of a bullet, but will they feed okay?

[RU shooter]

All depends or your pistol . I used to load a big heavy Keith style swc in my ruger P90 and the fed and shot fine but that gun would feed empty cases from the mag too . Load some dummies up and give it a go

The ones I tried in my 45acp didn't feed good I had hangs

Buffalo Bore makes a factory load.

You might have to tune the load to make it work in your pistol.

Sounds like a good idea to me. I use a 160 gr cast in 9mm.

+1 on the 255 swc. Hits like a sledge hammer. Feeds fine in my Taurus 24/7 and RI 1911

I used to sell a metric ton load of the lyman 452664 to the bowling pin guy's back in the day.
they were using them in their 1911's on top of 4-5grs of unique airc.
apparently that boolit will launch a bowling pin to the backstop.
anyway it's a 255 rnfp, it's my preferred 45 colt boolit but I haven't tried it in any of my shorter 45's I guess I should give it a go in the AR cases one day.

There are heavy bullets especially designed for the .45 ACP which feed more reliably than SWCs and intrude less into the limited powder space than Cowboy bullets intended for the .45 Colt.

I will be feeding it to a Remington R1 1911. Just an idea I had since I have a couple of molds in this design, Thanks for your input. I'll try a few.

I've loaded lots of them .I load them long just covering the top lube groove but the revolvers don't have to sweat magazine length .
I've run;
452-255
454424
454423
430426 , it was modified and dropped at 448 and paper patched .

Except the 430426 they all ran fine in 945 HP carbine at maximum magazine length also . The 430426 was an experiment for a Colts carbine ... It would pay better in a Casuall or S&W . I didn't have any left to try in the carbine .

I've loaded a bunch of the ideal 454-424 in a 1911, stupid fun and really nail steel. Keep velocity down and shoot it for what it is, heavy and slow. Loading these warm in a standard sprung 1911 is a great way to wear one out .

I've loaded Lyman # 454190 sized to .452 in a 1944 vintage Colt 1911A1. they fed just fine.

[MARCORVET]

Sounds good. I'll have to cast a few, the ones I have on hand are sized .454 for my 45 colt rugers.

You may have to run a throating reamer into your chamber. Lots of the newer guns have no leade.

Not doing that to my 45. It shoots 185's and 230's very well as is. don't want to ruin it.

[scattershot]

I think that a lot depends on the pistol. I tried it years ago with a. 1968 vintage Government Model Colt with no issues. Other guns I have tried don't work so well.

Traded for a RCBS 255 to 260 gr. (depending on alloy) mould in RNFP. Worked well and was very accurate in my .45 ACPs. You just have to cut back on the powder charge or damage to frame will occur. A friend who shot some of my stuff really liked the solid feel of recoil and accuracy. Big Boomer

They work fine in my gun. I bought a NOE HP mold, its 250gr FN without the HP pin, 230 with it. The external shape of the bullet has not changed in any way. I use that bullet in all my 45 weapons.

If it had the steep, abrupt leade most 1911's seem to have these days, don't be surprised if it shot the lighter boolits even better after throating.

As noted, depends on the gun but the Lee 255gr runs in all my 45s, 1911 or XD. SOft shooting at 675fps for gun games & a nice thumper round at 850fps.

I use the Lyman #452664 250gr RNFP in both Rock Island and Colt Series 70 1911s without any problems. https://www.midwayusa.com/product/31...rain-flat-nose
