Hey Chris, yes. 115 Rainier JHP's. It's compressed, but not too bad. Brass and primers look really good, but the performance is great.
I know guys do it, but it scares me a little. I have never used compressed loads.
Thanks for the info.
What gives you the impression that if the bullet is touching slower powder X there is more chamber pressure then if the bullet is not touching faster powder Y?
Every 9 major load I've ever loaded has been compressed to one extent or another and what I've found is that the powders begin to yield lower velocities when you push them too far, but the primers don't look any flatter. In fact, I see much flatter primers from shooters loading 124s over powder like autocomp than I do loading 115s over SP2.
