    Dropped it into a talo 6.5 cross that i did a bunch of load development on to try getting more accuracy out of the factory barrel. Didnt need the action wrench or sig barrel nut wrench. Just ar armorers wrench. At the range: Was shooting 143eldx loaded 20 thou long over 47.3gr stabal 6.5 in alpha srp brass, br-4 primer, suppressed enticer S Ti with 6.5 endcap. Noticed the velocities pick up in the first 20 rounds, shooting 5, cooling with bore fan, After about 40 rounds groups tightened up to very satisfactory, about .75 moa ish. Walked groups out to 600 with satisfactory results. Thats ma story and ima stickin to it. Gitchu one and gitchusum
