I plan to chamber my 7mm-08 24" Criterion barrel to 7 SAUM. I plan to use 168 vld hunting bullets as this will be a tactical/ hunting rifle. It will be on a savage SA and and will have a COL around 3.00" What kind of speed will i see with this setup? should i have a special reamer built or use sammi spec and have it throated for 168 vld? Any know any gunsmiths that have this kind of setup?
