I have a 1:8 Kreiger bbl waiting to have chambered. Trying to decide if I want a 6br or something else. I have 2 long range varmint rifles so I will be using the new one mainly for 300 yd shooting at 2 local gun clubs varmint shoots for fun. I want to shoot 95 or 107 SMK's. Am I on the right track or should I be looking at something else? I will probably use Redding bushing die, should I go with neck or full size? Thanks for any help.
