I highly doubt this. As previously mentioned the Germanyicon mainly bothered on the rifles that were in the identical 8x57 caliber as their own rifle (or pistols, where they anyway had a few more calibers in usage). The rifles not in 8x57 caliber were mainly put into storage. This storage was handed out in the last days to the Volkssturm - pictures proof the poor old and kids to carry many different weapons, including commercial hunting rifles (even shotguns).

The only difference to that is the usage of Sovieticon rifles on the Eastern front. But this was nothing officially done but rather the persons at the front used captured enemy material with the ammo they also got. Plus these also didn't got marked in any way.
