Ackley claimed he got 2700 fps using 3031. I recorded a speed of 2639 with a load that was below what he said was max, but it had pressure signs and I never got to max.

But I hunted with 150g bullets at 2560 and that is quite an improvement over what a regular 30-30 could safely do. That was 20 years ago and you may can beat that now. Good luck with it; it's a nice round.
