I have one in the works with a 30", 1 in 10 twist Krieger barrel. What bullet, brass, powder, and primer do you recommend for a starting point? On hand, I have WW brass, rl25, rl22, h1000, retumbo, us869, win wmr, some Fed gm215m primers, and 162 a-max's. Just looking for some time saving suggestions on accurate hunting loads.
