I have a pre 64 Super Grade with a 26" barrel. I've been wondering if I should cut it down to 24". It shoots 200 gr TSX's well but was looking for opinions as to barrel length and bullet weights. I do like the North Forks in general, as Uncompahugre mentioned. I shoot them in my 404 Jeff but haven't in other calibers.
By all means take the 300 H&H it was designed for use in africa. Just practice alot it requiers a magnum action so some short stroke the bolt in the heat of the moment practice will prevent this.
