Well, I had a .44 Marlin that I wish I still had, but this morning at 7:10AM, my 45/70 RUGER #1 Took my second ever cast rifle boolit critter.
A huge cow elk in a special, any weapon, anterless elk hunt.
The penatration of that 465gr. boolit was totally awesome even starting at shade less then 1700fps.
Figured I'd never retain a cast boolit shot into a critter with the 45/70, but this boolit stopped just under the hide on a front quartering shot, after taking out the front shoulder, a lung, going through the paunch and almost exiting the critter.
Liked the .44, but make mine a 45/70
Keep em coming!
