I certainly would not consider the 700 as a fantasy piece. I am sure you mean 4 oz. balls and not 1/4 oz balls for the 4 bore. I am with you on all the big calibers. Whether it is a 4,5,6,7,or 8 bore, they were all used to take lots of game and all were used successfully. I like shooting a true 2 bore, diameter 1.326" diameter. But I have never hunted wither either 2 bore that I own.
