Alright, I am back for more questions. The loads my buddy loaded up per the manual were too hot. This stuff was from the Barnes reloading data.

Anyway the minimum load started out at 78gr and maximum was 83gr. I shot one at 79gr and the case was a little tight coming out. So I went back and loaded one up at 76gr of 7828 ssc. Went back and it had a flat primer and a slight mark on the case but it didn't stick the bolt.

Some of my questions:
What effect do primers (difference in primers) have on the burn rate and pressure generated or do they not change anything?

I think I will go down to 74 grains and see what I can get out of that. I am thinking about trying some H1000 and Retumbo as well just for fun.

Any other suggestions?
