7 SAUM primers.

[Chrisjan]

I am building a 7 SAUM for 180gr Hybrids on a 30" barrel. It will be my F-class rifle.

I am planning to use H4831 or IMR4831. I will exclusively shoot only stick powders.

Would you recommend CCI200 or CCI250 primers? It is a matter of magnum vs standard primers?

I run BR-2's in both of mine. I saw no accuracy gains with 215M's. YMMV

I use standard Wolf primers instead of magnum. I don't know if the magnum primers would add anything in accuracy or ignition since I have no ignition issues with standard primers. Maybe a harder cup for higher pressures if you choose to load on the heavy side.

Thank you,

I will test both CCI and Federal. It seeems that Federal are sometimes the top choice for better ES.

You might want to try Rem 9 1/2 mags. Seems to work in mine better than 215's.
