I think I'm going all in on powder coating. I'm going to be buying a HP mold from NOE next week and am up in the air with which one to buy. They have a 135 with no grooves made for HiTek coating and the SC357-135-RF in RG4 PB blocks. Does one look any better than the other? Do boolits without grooves do any better or worse than traditional? I'll be shooting them out of an SR-9 for the foreseeable future but who knows what could show up down the road.
