i guess i should have specified....i want one powder for loading deer/ hog hunting rounds. ive used factory stuff and its worked great on deer and on hogs as long as i stay inside 50yrds. looks like the H110 is the powder for me! ill be practicing with the rounds, of course, but i might grab some unique for just plinking around in the off season. one last thing.....does H110 require a magnum primer??
