u/Optimal_Data_6627

Been working on some subs for my 762x39. First go around didn’t cycle. Tried Lyman book data on 150s and RL7.
Switched to H110 switched to a 220 gr took out the heavy spring I forgot I put in that and put in a lighter buffer. 16” upper. Lubed like crazy hoping these will make the difference. This is the first I’ve tried doing subs with this caliber.The Range Craft and gun will tell the tails soon!
