Just wondering which bushings I should get w/my redding 6BR dies. I'm going to use Lapua brass (if I ever get any) and the 105 Amax. Since I don't have any brass, I can't measure the loaded round and do it that way. I would just assume get the bushings along w/the brass and dies so I don't have to pay extra shipping. I also don't mind having a few different ones as I will probably want to play w/the neck tension. Thanks in advance, B.J.
