First time loading 9 Major (HS-6)

[kneelingatlas]

My buddy and I started reloading recently and I've been gathering lots of data (this forum is a great resource); we started with some 9 minor, then 40 minor, 40 major and today I tested my first 9 major rounds. The first question I want to ask is about the primers: I used CCI SRP which didn't flatten out as bad as some of the 9 major brass at the range after a match, but the primer seemed to expand into the firing pin well slightly. I remained consistent with all the loads from 153-179 PF, below is a picture with 124gn loads on top and 135gn loads on the bottom, highest PF on the left:

I shot two different pistols: my CZ TS (5.1" barrel) and a small frame Tanfoglio (4.1" barrel), the primers seemed consistent between the two. No big deal?

Here's the load data if anyone is interested:

I shot a few mags with 124s, then 135s of the same PF, the 135s were maybe a hair softer, but that could have been my imagination; they must have been a tick quieter because they had less powder, so that might have been the only difference.

thanks for the reference chart. i get similar results using 124 cmj mg out of my trubor jvi sti.
