Is the big bore irons only? my 450-H, does not have any iron sites, but I can use my 45-70 or 405#1, you guys make the rules, what ever works. But I will mention the 375 Mag. and the 9.3 are used on D.G. the world over, I don't have either one, just a thought. the more people we get involved the better. just my 1 1/2 cents worth. Blue
