Re: Rem 700 xcr tactical long range 300 win mag
I did not use Tubb, i had a box of 300WM FGM, took 1 shot, clean barrel, then took 2 shot, clean barrel, took 3 shot, clean barrel, took another 3, cleaned, one less set of 3, cleaned, and then did a final 5 shot group, measured 5/8-3/4 of an inch and called it good. That did take like 2.5hours to do all that, but thats how i brake in a barrel, with atleast 1 or 2 minutes between shots.
