      Anyone cast bullets for 300 blk?

      TLDR; Anyone cast for 300 blackout? Mainly looking for a plinking round at 100 yards. I want to load both Supers/Subs. I recently built a 300 blackout using an Anderson lower and a BCA 7.5", 1:8 twist complete upper. With 308 FMJ bullets coming out to 20 cents a pop, I found it way more...
