I found my rifle prefers 123 smks over 123 amax past 300 yards. The smks smoke them in group size for my 20" setup. I know a lot of the guys play with 107 smks and 108 lapuas for 600 plus. Can't comment on those loads but try smk 123 with xbr 8208. My rifle likes 28.3 gr seated at 2.230. Good luck in your quest for the perfect primer, powder, bullet, col length : ) and welcome aboard!
