I made me one of those gauges that clamp on the cleaning rod that you can slide down the barrel and set one with the bolt closed and one with just a bullet pushed up into the lands... Then I'll measure the distence in between and get my COL
I'm sure it will be longer than the Mag will allow... But at least I'll know my max distance...
That's how I do it for my Rem 700. Then I seat my bullets back 1-1.5 thousanth's for my OCL
