I've got 200 of these on the way to try in a remington with factory 24" SS barrel. I've got hornady brass and a bunch of different primers but don't have suitable powder yet. Does anybody have data or starting points with this bullet in 243? My first choice for powder is H1000 and H4350 but because of the shortage I'm open to others so all data would be appreciated. I do need to stick with a non temp sensitive powder since I'll be using this load for yotes, groundhogs, and some targets in the summer as well as deer in the fall. Barrel life isn't too important, it just needs to get me through deer season next year before needing a rebarrel.
