A friend and I were looking at one. I already have 4 various 45-70's, he has one. We looked up ballistics and decided there wasn't enough difference to make it worth while. How ever an AR-15 in 450 B. would be very interesting!

The factory ammo gives an edge to normal 45-70 and the Hornady has a lot more energy! This may have to do with AR plastic and heavy recoil. The bolt actions should handle some sort of +P load!
