So I'm looking at buying a 338 win mag with a 20" barrel as a multipurpose rifle for deer, elk, and hogs. I'm already thinking of what loads would be good for elk since some friends are talking about a trip out west. I would really like to shoot a 225 gr Interbond but wanted to see what powder would give me the best velocity to compensate for the shorter barrel. All the load data I have is showing a test barrel of 24" and I'm thinking the faster burning selections would work better. Any recommendations?
