I've gone up to 45gr of IMR 7828ssc so far. I have some more rounds loaded up at 45.5gr and 46gr that I plan on testing as soon as hunting season is over. Sorry no velocities , but I do have a chrono now so next time I will have some speeds. I also have some loaded with H1000 but I haven't shot any of those yet. Oh ya, Lapua brass, BR2 primers and the 105 hpbt's were molly coated.
