That is probably correct Winchester also produced model 1895's in 30-40 Krag and 30-06 Springfield in the hope of landing military contracts that never materialized. Remington was producing Mosins under contract for Czarist Russia right up until the revolution many of those were later converted to 30-06 Springfield and are unsafe to shoot.I was under the impression that more 1895 Winchesters were built for the Russians than all other model 95's combined. Eventually, the contract with Winchester died as the Russian Revolution took over the country. That left some of these rifles in the U.S. that never got shipped out.
What rifles were or are chambered in the very inexpensive and useful 7.62x54
I recall those days as well. When the only readily available source in the U.S. for 7.62X54R ammo. was from Norma at around $30 a boxBecause I recall a time when the answer to that was "none", based on the word "inexpensive".
There was a time, and a long time too, when Russian/Soviet rounds were not inexpensive, and were not common ammo. A time when .303 British, 8mm Mauser, and even .30-06 (Surplus) were inexpensive.
