I have a Remington 700 BDL 22-250 with factory heavy barrel that I purchased at a gun show used. I had my gunsmith mount and boresight a scope for me. Now, I'm ready to take it to the range to shoot it tomorrow. Do I need to worry about headspacing? I always have old milsurp bolt actions checked by a gunsmith.....but just wondered if I should with this 22-250???
