Nothing that hasn't been done here before, except for the rifle. Member frkelly74 was gracious enough to send me a few of the .224 Lee bullets powder coated. Some were GC, some not, and I give you some photos of the testing. Only ten rounds involved due to very limited supply, but I learned something
That blow by was nasty, and only in the H-335 load. The Win 748 load produced very little blow by fouling.
Functioning was perfect, no issues feeding. I think I learned something and intend to explore further.
