PRC bullet seating depth

[quandary]

As for the literature stating "the PRC specs are much more stringent", that is hype from Hornady. There is still a SAAMI spec. It is no more or less stringent than any other cartridge. Especially when the best reamer design for the 7PRC is the 7PRC AW reamer...

Not to speak for the OP...... SAAMI specs for a chamber are precise regardless of cartridge. I think what he meant to refer to is the fact that the SAAMI chamber specs for the PRC to the SAAMI specs for the cartridge provide for much smaller space between the cartridge and the chamber wall than traditional cartridges. Which is true.

I agree with that.

I agree with that.

Lance I know you have a prc. Have you had the sticky extraction issues?

I had a 6.5PRC, cut with the AW2 reamer. Used Lapua brass, had 14x firings on it with zero issues. Smooth like butter.
I have a .300PRC, again, cut with a modified AW reamer, just a touch less FB. I have up to 3x firings on Lapua brass. No issues. Very smooth, and it is running on the "warm" side. 230s @ 2995fps.
I have loaded for a few different 7PRCs now. When using Peterson or ADG brass, no problems. When using Hornady brass....yes. Clickers and bolt lift. I think a lot has to do with garbage brass.

I have a large base reemer for my 6.5PRC, Lapua brass, no issues. My 7PC and 300PRC are SAAMI reemers. On those I double size. First with the Forester FL bushing dies, than the Cortina mandrel sizing die made to deal with the clicker issue. It puts my brass back to .532 at the .200 datum line. So far so good but kind of a PIA. Will likely rent some AW reemers at some point to clean up the chambers.

That's not true. I'm really not sure where that myth ever came from.

Anyone can look at the drawings on the SAAMI website. There's no real difference when compared to anything else
