7mm PRC

[Mumzergadol]

This is

180 eldm
rl26. 66.5gr
Norma brass 2x
215m primer
Gives 3015 and SD 7

Was actually fussy about seating depth. Shot well at. 005 and .050 and nowhere else.

Bergers 184 worked across a broad range of powder charges. This was 66.5 and 66.8

As a follow up question - who has found an acceptable powder in LRT, Magnum, Retumbo, etc. my bbl doesnt love h1000, and it could be 2 years before i find another keg of rl26 (which i burn in my 6.5prc as well)

anyone?

What bullet weight? I’m using Retumbo for Berger 190s and it is getting near 3000 fps in a 30” barrel. SDs are a bit higher than I prefer, but results on target have been very acceptable.

either 180 hybrids or 184s. Might try the 190s.
26" barrell

I've had good luck with Ramshot Grand, velocities up there with RL-26, temp stable and available. Staball HD was ok, but didn't really live up to the billing for me, unlike Grand.

I’ve heard that about Ramshot Grand. Not tried it.
