I have data from a guy that ran an experiment for Freedom Arms in loading the 454 Casull into a lever action..The Marlin '95 action was the first to go with a steady diet of 62,000 PSI in something around 20 shots fired,then next was the Winchester '94 with about 40 rounds fired..Both actions gave up the ghost..
One must also remember Winchester came out with the Big Bore version of the original '94 action which was alot stronger..Winchesters new Big Bore could handle the .307 Wiinchester(52,000) with ease..
Marlin then came out with the .307 Winchester in there '95 action(slightly stronger than the 336) and quickly took it off because it could not handle the pressure.
