I wouldn't mess with Retumbo...It's a very picky and finicky powder. I attempted it in about four rifles and could not get it to shoot consistent at all.

R#twenty five which has a earn mag primer is yet another powder that works great Along with the 160g course bullet with really small SD.

seeking ahead to the results. which is a single powder I used to be considerin, but I've a crap ton of 7828. I hope I am able to use it, however, if I can not discover precision with it, then I am relocating on.. click on to extend...

all of them checked out wonderful. "reserve load". pondering it was a whups to the chrono's component, I very carefully loaded a few far more and went back on the vary. identical fps studying on the initial shot, so I finished shooting 'em and gave up on that load.
