Re: 7 BAT
I'm not sure that surgeon will have a 7Bat reamer, They used mine to build my gun, And 300wsm winchester brass is too thick in the neck to use in place of norma. AND I cant make my winchester neck down right either. So between havin to neck down and then turn your winchester 300 wsm brass and order a reamer.
Why not just swap someone your 300 brass for 7WSM brass build a 7wsm not have to worry about working up loads that noone knows (and no they arent the same as 7wsm) turning necks and necking down?! Everyone has 7WSM loads! But id=f in spite of all my reasons you still want a BAT, Pm me and I will give u some good loads and help you spec the reamer
