For some reason I am getting a hard bolt lift...Lapua brass
full length sized..Fired probably 8 to 10 times..
cci 400 primers..powders used Varget-re-15...Bullets
107 sierra-85 gr bergers-95 grain bergers..

all loads started from the min. load listed..Bullets not
jamed into the rifleing...The very starting load is causing
a hard bolt lift.

Not sure of the chamber as I bought the barrel used and he
said he got it from Briggs..C.B.I BARREL 1 in 8 twist..

I have tried the 6br norma as well as the 6br Rem data..
Checked case length..within spec..Rounds chamber with ease..???????????
