Did some 300blk load development today with the 125 grain Sierra Matchkings with Accurate 1680 at 75 yards.
The factory 147s were used to zero the Trijicon MRO which was previously on my Noveske 5.56. You can see as the loads got hotter the groups got tighter. 21 grains is the max listed load but there were no pressure signs and based on that group....no need to go hotter. I still want to try H110 and Lil Gun with these projectiles but I cant imagine a better result. These were fired from my PWS MK116 Mod 1.
I fired one shot for each group and then used that as a reference point for the 4 follow up shots.
