Shot some test loads to get a start point with the rifles and magneto-speed off the porch.
M70 (22" bbl)
150gr Hornady, IMR 8208XBR, 2.966 OAL, WLR Primer, Nosler case
45gr 2557fps
Starting load will be 46 grains. If all things hold true, I'll find a good load in 2750fps area.
M700 (24" bbl)
175gr Sierra, IMR 8208XBR, 3.05 OAL, WLR Primer, Nosler case
44gr 2478fps
Starting load will be 45 grains. If all things hold true, I'll find a good load in 2650fps area.
Some clean burning stuff though.
