Up to about 40000 PSI, the Marlin can take it. That is a lot of 45 Colt load. Linebaugh only recommends loads up to 32000 in a Ruger, 80% of a 44 Magnum load. Also, The folks at Oregon Trail Cast recommend that there bullets be shot at around 1200 to 1500 FPS Maximum. That is very easily done from a rifle bore.
