The cases could be too thin, either way dont shoot them if you can push the bullet in.

Yes, R-P is remmington and it's a common issue. I save the Rp when I load lead projectiles @ .452 and it seems to work better that way.

Have you tried using a heavy crimp with a Lee FCD? I've been reloading .45ACP with RP brass and Hornady 230 grain XTP's for about a year now and haven't had any trouble at all...

Have you measured the bullets? Are they under spec or something?

The only brass I have ever heard this complaint with is Remington. I have over 2000 cases and have never experienced any trouble with it.

I make sure my die and shell plate are touching or even camming over slightly, this goes as far as possible toward sizing as much of the case as you can.

I use a .470" or .471" neck dimension.

I only flair the case enough to set the bullet in it. Any crimp really, is just the removal of that flair.

If I use Lee's FCD, it's only to apply a light crimp. 90+% of the bullet retention is the responsibility of neck tension from the resizing die. If your's doesn't give enough of it, send it back to the manufacturer.

My father-in-law gave me several hundred nickle plated Remington 45 Auto cases.
None of them even with a heavy taper crimp would hold a bullet secure enough to prevent finger pressure from setting the bullet back in the case.
I was afraid to shoot them. I pulled the bullets and tossed the cases.

I've never had that issue with plain brass, R-P or otherwise.
