My thanks to Damnesia for his empirical data on early first version 250-3000s, circa 1915. Yes my Savage rifle #17255X, like yours is able to shoot 90 grain Sierra Gamekings and the shorter 87 grain bullets but not the Sierra 90 grain BlitzKings which were simple too long and tumbled and keyholed at 50 yards. My THANKS! Incredible knowledge seemingly only found on this forum. (no free bore - no replacement barrel needed!)

Looks like somebody did some very respectable work on an early Model 1920, serial # 1039. Guns International #: 101961008

There is also a newly posted example of an engraved Nieder Mauser Kurz rifle.

Beautiful examples of 250-3000 rifles from another age.
