The reality that the H4831 is in fact a slower burning powder is specifically why you might be looking at increased velocities attained with that powder, instead of Everything you've witnessed with the IMR stuff. Also excellent powder, but rather better suited to somewhat more compact conditions with a bit significantly less capability.
