I bought a 6mm ARC barrel from you guys not long ago. I have been extremely limited in supplies because 6mm bullets are vaporware. I started out trying some 112 Barnes bullets but the other day I found a single box of 108 grain Hornady.
Today with my very first load these were the results. No charge weight tests nor any seating depth tests were done yet using those bullets.
The group measures .517 inches from outside edges which makes it .27 inches center to center. Since one MOA is 1.08 inches that works out to be exactly a .25 MOA group.
