Winchester Brass, CCI Primers, Varget Powder, 55gn V-Max 13" AR-15 1-9" twist rifle barrel. (3" Novske Flash suppressor welded on to make it 16") Custom Built on DPMS and holds good groups. Trying to see if there is a pet load out there for these. Have 29 and would like to see how good they preform rather than waste most doing load development. Thanks.
