I've only been using Fed215M primers and Peterson brass.
FWIW - I've transitioned to using a mandrel on all of my reloads. Bullets do seat more consistently but I'm not sure that I can see any difference on paper.

I'm running .004 with mine, with Peterson.
ES /SD is much improved.

Doing load development now for 7prc. Rifle is Savage Ultralite with 22" carbon fiber Proof barrel. Using both Hornady 175 ELDX and Berger 175 elite hunter. Powders are Retumbo, RE22, RE25, RE26, H4831SC, H1000, N568. 100 yds for load testing. Velocities ranged from 2800+ to 3078 - and tracked using the new Garmin Xero c1 chronograph.
Didn't have good luck with group sizes for Retumbo or RE22. Best group size with Hornady 175 ELDX was with RE26, 68.0 gr, 2992 fps. Covered group with a dime.
I think my rifle liked the Berger 175 elite hunter bullet better than the ELDX. Very good results using Berger bullet with powders RE25 - 2892fps, H4831SC - 2867fps, N568 - 2883fps. Highest velocity with this bullet with H1000 - 3063fps.

3063fps is moving right along from a 22" bbl. What charge weight are you using with H1000 and the Berger 175 Elite? Primer & brass?
Was using load data from Berger on their bullet for 7prc. 70.6gr of H1000, Hornady brass, Fed GM215M primers. Highest velocity for the 3 loads I put together for this powder was 3078.

I'm still working with my 7PRC. I'm running about 2,900fps in a 26" bbl. Looks like there is still some room on the table. Thanks for the feedback.
Yea, was surprised as well to see a velocity over 3000 for a 22" barrel. No indication of any pressure issue either.
