Just got into the suppressor game .... looking to roll up one load for several rifles, both bolts and DI AR guns ..... been reloading for decades now, but this is a new wrinkle for me .... all guns are relatively short barreled (in relation to my 24" barreled 270WIN hunting rifle) - 16"-20" .... any powders or bullet weights I should check out first for best performance with the can on? Been running WWB 150gr PP in the kids guns, so far, and just realized I had several hundred empty cases needing something done with them ..... thoughts?
