Looking for a 6mm PPC load

[mleeber]

Evening! I have a new to me 6mm PPC AR upper. Not sure who made the barrel but it is a heavy 24 inch job with a 1 in 9.25 twist rate. I have some 70gr SMKs and 105gr Hornadys on the way to test the upper. Looking at N133 for the 70s and Tac for the 105s. Anyone have a good load for either bullet in these powder combinations? I also have Varget, 3031, 4198, 4227, 4831, 4895, 4064 (all are IMR not H), XMR2015, Win748, RE 7, RE 15, RE19 and RE 22 on the shelf. I will be working on 300-600 yard load eventually with this upper.

Thanks!
