Yep 7mm rocks BUT!!!!!!! only in the 180 and 190 grain bullet weights then they are cruise missiles......I had that dilemma as well I almost built a 7 MM STW with a special reamer just for the big 7mm but the components are very hard to find to load so i went with the 338 that gun Eric will be a real laser beam when you get it tuned can not wait to see it...
Oh hell yeah ! !!!!! you get with it you crazy Canuck I like it get you some 180 or 190 Berger hybrids and send it ! are you going to bring it with you when you come?
you can save yourself a ton of components by just firing 3 of each and make your groups smaller start at 10 off jam then go to 30 then 60 that is three shots each 9 rds total you will know from that where to refine and if you shoot two rounds and you see they are now ging to group don't fire the third round save it for a fouler or barrel warmer.
The wilson Sisters have been long time Led Zep fans in their concerts there was almost always a Led Zep song in their concerts seen them many times they kick a$$ on Rock and Roll and Black dog as well that woman is the best singer I have ever heard live.
would it help if you deprimed all cases with a stand alone decapping die? just wonder is the neck sizing ball added to the strain on the brass? interesting glad you did get it figured out.
