40s&w R-P brass -- is there a resizing die that will work?

[m0par]

I bought a bunch of "once-fired" mixed .40s&w brass.

The Remington brass won't hold a bullet. Light pressure will set back the bullet.

I see this isn't a new issue. Problems have been reported before with thin R-P brass having no neck tension.

I am using RCBS dies. I was just wondering if one of the other manufacturers makes their resizing die a few thousandths smaller, to minimum spec or something.

There's not enough R-P brass in the lot to make a custom die feasible, but if anyone is having good luck with reloading R-P brass, whose resizing die are you using?

Call RCBS. They will get you a tighter sizer. I have 3 .45 sizers. One won't work with RP brass. I don't have a problem with RP in .40 brass. The carbide ring on my .40 sizer is .415 ID. (At least the one I am using. I have another one around here somewhere)
