Guys, I'm a die hard 165 grain bullet fan. What powder would you most recommend for a 30'06. I've been using H414 for years, just because "it worked" but my case necks keep coming out filthy. I'm beginning to think the 414 burns dirtier than some other powders and would like to try something new and don't want to waste a lot of powder, searching for a new load. Thanks for all the feedback.
