I'd not use an original Springfield of any vintage unless loads were kept at original factory levels only.
: Original ballistics of the .375 were for 2,400fps with 300gr. bullets and 2,600fps with 270's. Those are the 'factory' levels I spoke of.
: These seemingly low-power ballistics are the loads the .375 gained it's enviable reputation on.
: I personally believe that velocities above 2,400fps to 2,500fps are not needed nor desired and with normal bullets at normal game ranges.
: Today, we seem to be locked into a magnumitis-required society, which, of course, was developed by compainies needing to sell us 'something new' to keep us buying. Without this need or desire to go faster, hit harder, and have extended range, we'd only have a few rifles to use for all our game shooting and actually we'd be better shots due to our familiarity with them.
