For the 243 I use only IMR 4895, it is at a burn rate to fit that caliber and defence capacity immaculately. I am a IMR fan because it have a very appropriate and stable shelf life, as anti some other brands that tend to get hotter beside age. The IMR 3031 is a little faster contained by burn rate for my preference surrounded by the 243. The IMR 4350 is way too slow a burn rate for such a desk light caliber with that powder size, IMR 4350 works great for light bullets contained by the 25-06 case continuum but not the best for 243. When I work up a new caliber I try several of the IMR powders and agree to the most accurate group determine the powder burn rate that is best suited for it. I oral exam several 100 rounds before making the send for. For the 243 it preformed best with IMR 4895 and next to the IMR powder if for some reason the loaded shells don’t acquire fired for some time, they will shoot the very same as ammo made near fresh/new powder. I really don’t know why I am conserve
