Dober thanks, I like the idea of a 1-10" twist, 25-26 length. I have a 280AI O9 mauser with a Pac-Nor barrel that shoots sub moa. I will talk to Chris at PC about a 6mm. what are your thoughts on R17 I use H4831 in a 338 that works well, it seems to be fairly stable in temp. changes. I have been using tsx's in all my hunting loads the past few years. I find them very acurate and perform well on elk and deer. Dober once again thanks, 6mm-06, 85tsx sounds like a good yote killer.
