My first guess was 350, but I've been off some before. Typical for them to run 30-40 yards after the shot. Ought to make a nice mount.
You have probably already figured this out, but quartering away shots work well, actually better than broadside. If you try to visualize the bullet path and get it in behind the shoulder, they rarely run very far after the shot. Hogs can be tough. The heart in a Hog can be lower than you'd think, it is tucked in behind the shoulder and protected well.
