I had a good load worked up for 300 grain hardcast in my Dan Wesson .44 mag, but can't find the data and don't remember what powder I was using, this was 5 or 6 years ago. The only hangun powder I have right now is Unique,. Anyone have a good HEAVY load for 300 hardcast with that powder? From the little I read in a couple of my books, V110 might be a better choice? I'm wanting 1300 fps (8" bbl). Any other suggestions?
