FWIW, there was a .25 Stevens RF SHORT and a long. The short went out of production in 1951, the long in 1960. (Source- US Cartridges, Chas. Suydam) I THINK the last production runs were Dominion in Canada. BTW, if you think finding THESE is hopeless, there was another .25 RF that does not interchange with the Stevens- the .25 Bacon and Bliss. I have one round. Made from 1861-1910.
