Even though I have had zero issues with my Marlin 45-70's pressure or other wise,the Marlins are not perfect..I doubt Ruger will change anything but one can hope..
The Marlins are not necessarily easier to work with. Matter of fact, they can be quite finicky when it comes to making them digest fodder for which they were not originally intended. One of the main Marlin complaints I hear from CAS shooters is that their Marlins will suddenly develop feeding and digestion problems, which can only be remedied by new parts, or by judicious welding of the old ones. They are notorious for failing to stop cartridges from advancing out of the magazine, at inopportune moments, jamming a fresh cartridge under the carrier/lifter. Only a major inconvenience in a CAS match, but a real disaster in a real-life situation.
Other differences aside, the Marlin WILL handle loads in the 40,000 - 45,000 psi range all week, with a double helping on Saturday night - as will the '94 Winchester - but there's a BIG difference between that kind of pressure and the 65,000 psi generated (and SAAMI-allowed) by the .454 Casull. Neither the Marlin 1895/336 nor the Winchester 1894 was designed or manufactured with THAT kind of pressure in mind. My own rifle was put together with exactly those high-pressure parameters foremost in mind.
As Jim Taylor said, the data is there, and the results are irrefutable.
