Max-pressure loads and a long barrel let my '06 do pretty well in the velocity department. 150-grain bullets somewhere near 3,150. Way back when, (okay, 60 years ago) I loaded 80-grain .32-20 bullets ahead of some 54 grains of 3031, which would be up near 4,000. (Ruinacious on jackrabbits).
I've never had any problems for accuracy with the 1:10 twist.
I tend to think that folks worry too much.
