IMHO you could shoot anything in it. After awhile it may become loose, so I'd keep loads 7000psi or lower. I just sold one in " good " condition for $400. I've seen them advertized for up to $1000- but I wouldn't pay that. Now a 1894 Remington is a different story. The insides of both are much like a Ithaca NID - just what was needed, not a lot of extra stuff to break, nice to work on. The 1894 had a Purdey pushbutton type of release on the forearm which is much nicer than the snap on forearm of the 1900. The high end 1894s sold for as much, or more than any gun of its day. The 1900s were as well built, just not as nice. Paul
