Shame you have to sell the other 2, but I think you will find the 450/400 3 1/4" is a most excellent calibre.
Mine has killed deer, several pigs, 2 caribou, and a black bear. Either one of the 450/400's is probably the best allround double rifle calibre for the modern sport hunter.
I sure wish Chapuis, Heym, etc. would make them.
My rifle weighs 9 1/4 lbs and is a joy to carry and shoot.
