Finally made my first range trip with the BRA. Barrel came in Thursday so I spun it on and loaded up 50 rounds to do some break in.
Ended up finding some 107 Matchkings so I loaded those in Alpha brass, 30gr H4895, and 205M primers. Velocity was 2,913 fps and accuracy was amazing. The 3 - shot group below were literally shots #4,5,6 through the barrel. I did see some ejector marks on the brass, so considering it was 20 degrees out I think I'm going to work up a low node for summer.
Kinda feels like going to the dark side since this is both my first custom rifle and my first 6mm hot rod cartridge. Blew my mind how easy this was. I'm definitely hopping on the band wagon
