I'm a firm believer in useing enough gun but I don't think most hunters need anything more than a 308 based round. The people that ask if they need a magnum are the one's that probably don't have the shooting skills to take advantage of the extra power. Shooting a 100lb doe at 50yds with a 300 magnum doesn't make sense to me but that is better than shooting deer at 300yds with a 22-250. I'm not anti-magnum I just don't think that a magnum is always the best option.
