I’m looking to try some heavy slugs in the 700mm M3. I’ve seen slugs from 50-78grains that will fit with my CARM single shot magazine. I can’t seem to find any reviews with ammo heavier than 46ish grains. would love to hear some results with heavy weight high power tuning!
Impact M3 .30 Slugs 50+grains? Anyone?

What are you getting for velocity’s? Reg pressures? I’d love to be sitting around 1010fps if it will print well

I used to shoot the NSA 49.5gr HP at 980fps out of my MKII P/P and standard superior liner. They would group MOA at 100 yards easily.

Not even close to 1k. Reg 1 was 185 / Reg 2 was 133. 850 fps was the top. I was using an FX Chrony for feedback.
Probe was original, small adjustments to Micro and Valve were the only other changes made
