Don't sport it: restore it. There aren't enough of those around any more to risk losing another.
BTW, the standard load for the 7.92x57JS at that time was a 154-grain flatbase spitzer bullet, and these rifles shoot very nicely when fed those. The 196-grain BT was originally the ANTI-TANK loading that was issued only to machinegun crews, the theory being that the locking mechanism in a 98 weighs an ounce, the locking mech in a Maxim weighs a pound. Everybody had pals in the machinegun section, so guys "appropriated" a handful of rounds, just in case they got in bad with a Tank, but it was never recommended for use in rifles. It was Hitler who standardised on the anti-tank loading as the new "standard" loading for Mausers so, if your rifle kicks too much, blame him!
I load for my Great War Mausers with ammo that will duplicate what they were designed for, and they shoot very well indeed.
Have fun.
