I going to be loading up some rounds for my .243AI. It has a 22" Douglas barrel. My question is what powder should I use that I will get the most out of?

I have a bunch of Varget on hand that I use with my .308. I like it because I shoot in a broad range of temps and it seems to stay constant. Does Varget burn fast enough to use in a 22" barrel? Would I be better off with IMR 4831 or 4350?

What velocity should I expect with a 75gr bullet out of a 22" barrel?
