I'm having a smith blueprint the action on my SA Remington 700 and rebarrel it with a new, 22", 11.25 twist, Bartlein barrel. The barrel will be chambered in 308 Winchester. He's asked that I send him a dummy round that he will then use to tailor the chamber to my reloads. They will consist of a 175 gr SMK in a Lapua case using Varget and 210M primers. My question is what should I set the COAL at to where it touches the lands? Where would you set it if it was your rifle? I've already checked my rifle and the maximum COAL that will fit in my magazine (AICS) and reliably feed without hitting the feedramp is 2.875". I would like to keep it short enough that I'm able to chase the lands as the throat erodes. I was thinking of setting the COAL at 2.820". If the bullet is touching the lands at that point, I can back off to 2.800" when I start doing a OCW workup on the rifle. Then when I have a good powder charge identified, I can do a seating depth test from touching the lands back to .040" or so off the lands. Setting the COAL at 2.820" (touching the lands) would leave me .055" to be able to chase the lands as the throat erodes and still be able to feed from the magazine. Does that sound feasible? Your thoughts on the matter would be appreciated! Thanks
