My M70FW shoots the 130 Interlock (flat base) best, but my Ruger M77 prefers the 140 Interlock (BTSP), here is my load:
W-W cases
WIN WLR primer
Hornady 140 BTSP (Interlock)
57.0 grains H4831sc
Velocity ranges from 2810 fps to 2835 fps from the 22" Ruger barrel, with the Beta Master Chrony set at 10' from the muzzle.
This round shoots from 3/4" to 7/8" (three shot groups) @ 100 yards in my Ruger.
