Re: 75 a-max in a 1-9 twist?
I think it depends on the muzzle velocity. They would not stabilize for me in a 24" 1:9" Savage 10FP, and the HDY BTHP Match would. But, I was also running a slower than usual pawder; and the MV may have been just slightly insufficient to achieve enough bullet RPM. I was not concerned with shooting beyond 200yd so velocity wasn't the issue, accuracy was, and the BTHP Match was very good at the particular loading (26.5gr(C*) of Ramshot Big Game). Good (1/2" at 200yd) accuracy, no pressure issues. I think a faster powder would work better with the A-max, but then the pressure issues would become relevent.
