*Load at your own risk*
Goal achieved. Both loads capable to 1000+ yds, very mild recoil, efficient, temp stable, groups well.
Many thanks to the Little Crow Gunworks YouTube videos on reloading.
I think that this is similar to the journey Frank is on with his podcast but with factory ammo. I had the pleasure of learning from him at Treadproof and brought up the idea of a bolt gun in 6 ARC as it was coming online in 2021, but I am a poor so it took a while to get it built up and load developed.
Anyways, here are the groups and data.
Temp 59F, Humidity 63%, 29.93 mm Hg
1. XBR 27.5gr, Hornady 103 ELDX, Alpha brass, CCI 450 SRP, .010” off lands, minimal crunch with seating
2. XBR 27.0gr, Hornady 105 Aeromatch, Alpha brass, CCI 450 SRP, .010” off lands, no crunch with seating
Minimal cratering, no shiny spots, easy bolt lift.
YMMV and happy shooting!
