My loads for a M70 24" barrel, full length bedded, 3lb trigger. All these loads shoot 5 shot groups 1" or better @ 100 yards:
Speer 200 gr. JFN - LR Primer, 67 gr. H4895, tickles 2,800 fps MV
Speer 235 gr Hot Cor SP - LR Primer, 73 gr. H4895, tickles 2,800 fps MV
NAB 260 gr, - LR Primer, 69 gr. RL15, tickles 2,650 fps MV
Hornady 270 gr. SP - LR Primer, 75 gr. RL15, ~2,750 fps MV, 0.030" off the rifling, probably my most accurate load
Swift 270 gr. A-Frame - LR Primer, 74 gr. RL15, ~ 2,700 fps MV, 0.030" off the rifling
Hornady 300 gr. RN - LR Magnum Primer, 77 gr. H4350, Compressed load, ~2,550 fps MV, ~1" groups. Switch to LR Primer, ~3/4" groups.
Woodleigh 350 gr. PP - LR Magnum Primer, 68.5 gr. H4350, ~2,250 fps MV. Load data supplied by Woodleigh.
That’s great info. I would love to build loads from 200 to 350 for the 375 I have on order. Would be a great way to learn a rifle that could go from coyotes to Cape buffalo...
