COAL - Compressed Charge?
Good thread. I'm planning on working up a load for my Rem700 .308 Winchester with the same components (I've had good results with IMR XBR 8208 velocity / accuracy wise). According to Barnes, the minimum velocity for expansion is 1600 fps, making the range about 600 yards for a .308 175 LRX bullet.
I see you've posted the the OAL from base to ogive. Did you record the actual COAL from base to bullet tip? Also, are you running a compressed charge?
