I am not sure that there is a major difference in the rifles. I thought there was a progression in there of MK - Wolverine - Big Horn but i am not exactly sure.

The only real differences I see, would probably be the reciever shape, probably the trigger, and after that they are pretty much the same.

One other thing - the Big Horn will come with all 3 ignition systems, while when the MK was made nobody had really thought much about a 209 ignition.

One thing I can tell you shooting the 90 grains of T7-3f with a #11 cap - it was not necessary to damp after each shot - I never had to run a patch - just load and shoot.
