RL16 and 75 ELDs for me. Not quite kissing mine @ 2.650" COAL. Case fill seems about ideal, not compressed but it's nearly full. Upon further testing, 37.0 Grains shoots best(sub 1/2 min) and has me at 3,300 fps at the muzzle. 37.2 & 37.5 grain charge weights opened up to MOA.

Work up and don't take my chrono data as gospel. I verified the 3,300 fps at a distance of 615 yards. It was money at that range.
