I like 66.2 gr. of RL17 with a 215M in Winchester Brass with the 230 about .030" off the lands.
Gets me right under 2900fps with single digit SD for average of 5.
At first I tried .005 in to .010 out and just wasn't too pleased with the consistency. Went back and played with it and found they liked alot of jump in this barrel. 3/8-1/2 MOA consistent now.
Also really loving the 208 AMAX with 68.5gr. RL17 in FC Brass and a 215M. Those are jumping .015" and giving me 3060fps
