I have wanted one for a long time now and with all this 45-70 talk I am very close to plopping the money down. Only choice now is the 10" or 7.5" barrel. I know with 33 cal and less you need that extra barrel to get good speed. I was thinking with a large cal you have more volume for that powder to burn so mabe the 2.5" might not be worth it. Besides it's harder to quick draw a 10" barrel.......what do you guys think.
