Thanks for all of the responses, everyone! As usual, Freepers rock, and I got lots of good, interesting info from you!
As it happened, today I found a Mosin-Nagant at a price I liked, so I brought that home instead. My wife was very excited about be getting it- even insisted that I get it before leaving the gun show, as it might not be there tomorrow!
In the future, though, when I am set up to reload, I may well take another look at the Steyr- I just liked that gun!
Good choice. Inexpensive gun, way cheap surplus ammo, and several manufacturers build hunting rounds.
