Still waiting on Leupold, I couldn't take it anymore. So I just mounted up a scope I had and I'm going to break the barrel in tomorrow with some Sierra 160 BTSP, Hornady 162 BTSP, Nosler 160 Partition. All on top of 64grs of H4831SC, all seated for a .010 " Jump ".
I'll check velocities and accuracy from there and adjust accordingly.

I fired one round out of it yesterday, so I could use the spent cartridge for my AOL. Recoil was NOTHING, it's a total pus sy cat. A nice change from that 450 Ultra Magnum.
