I just got done loading 50. 15 each of 45 grains, 45.5 grains and 46 grains of Varget and another 5 with 45 grains for sighting in. I used some R-P once fired cases I didn't know I had and used Winchester large rifle primers.
I'm going to shoot 15 shot groups out of the lead sled and shoot over the chronograph while I'm doing it. Probably all three loadings will shoot well, but I hope the 46 grain one is best, because I'm fairly certain it will be the fastest. I hope I get 2600+ fps, we'll find out for sure next week.
