Great Caliber---see a few in the model 99 off and on--have only read and heard great things about it..per my info out of hte BLUE BOOK OF GUN VALUES..they were man. between 1920 -1931--states the value is increased for this caliber (250-3000)--besides this caliber also sold in .300 Savage..

Further states, the model 1920-1926 is similar to the model 1920 bu with a 24" barrel and Lyman aperture sight-manufactred between 1926-1931..

John Barsness recently had an article on this caliber in RIFLE SHOOTER magazine as well...
