Here's what I've loaded so far.. This is using precision delta 115gr FMJ round nose Load 1 = 4.0gr @ 1.150 OAL - Cycled fine, but recoil was so light it didn't even seem like worthwhile practice Load 2 = 4.5gr @ 1.145 OAL - Extremely hot round. Cases looked fine but the guy at the range said it looked like the primers were melting a bit, I'm not so sure that's the case but it was definitely a hot round, I didn't even want to try it in my PM9 Load 3 = 4.0gr @ 1.13 OAL - only slightly less than the above in terms of felt recoil, more managable though. All of the above loads were very dirty on my gun, the last two weren't as smokey but still quite dirty. I just loaded 50 rds 4.0gr at 1.14 OAL, hopefully that will be the sweet spot I'm looking for..
