I have one particular rifle that prefers mid-list powders run HARD regardless of bullet weight. Often I am well above published data before a high node appears with a 4350 burn rate powder.
The benefit is almost always good groups, low spreads, great velocity, and higher recoil. I almost always stop before I get a pressure sign but I know the pressure is on the upper end.
When a slower burning powder is selected groups go to hell.
The problem is, it makes me nervous. Has anyone else experienced similar patterns?
