I’d try all but 223, as it’s a bit faster than the others. That said, I’ve heard of others, having success with it with light bullets meaning 120 or lighter.
I’d try these 2 first: Varget or StaBALL 6.5.
Unlike many others, I couldn’t get Big Game to shoot in my 708. It does decent in my 22–250. I don’t like how it measures in my RCBS charge master. The powder is like mini basketballs, it gets messy! I’m still trying to find someone to trade off the big game power I have left.
