7mm Valkyrie AR Mule Deer Load - 09/17/15
I finally got my 7mm Valkyrie AR built. Its designed to get 7mm08 or near 7mm08 factory performance from an AR15. I just got it all together this week and had one trip to the range to get my hunting load for my Mule Deer trip in 8 days to the Sierras so instead of working up from scratch i sort of cheated and used a pet load of the cartridge designer to get sighted in and it worked for me so i stopped there and didn't try anything else i have loaded up. I'll play around with other loads after the season. The pet load was a 140gr Nosler BT with 38.4gr of Leverevolution powder and gave me a MV of about 2720fps. I chronied 3 shots at 2736, 2711, 2717 from a 22in 1/8 twist barrel. I didn't form the brass i just bought it preformed from the cat developer. The rifle worked like a champ cycled perfect, ejected each round and the bolt stayed locked back on the last round fired.
