Curious to see the responses to this as I have a 45-70 Marlin Guide gun --just recently ordered some hot ammo for it..plan to use for a camp gun when camping in Griz. country..as well as some close range whitetail hunting..

Remember reading that Jeff Cooper had once reported of some using Marlin 45-70's on lion for the quick follow-up shots.

IMHO, similar to 458Win --only a tick or two slower in Velocity..
