I have one in 30/30 it is a great shooter. It was given to me by a friend and it was in a bad way with rust but the barrel rifling was in good shape so I went to work on the rust and then reblued the complete rifle. It is a show thing now and it is a great shooter. There are a lot of parts around for it so repair is easy. I hope you have as much fun with yours as I have with mine.
These and the Stevens 325 in 30/30 are some of my favorite starter deer rifles. I've bought 5 of them so far for nieces and nephews and I hope to get one for myself some day. They are accurate, light, and can be found very reasonable. I buy them every chance I get. With 150 grain spitzer reloads and a scope, they easily take deer out to 200 yards or so. The only negative is that I have run across three that had excessive headspace, enough that the primers were partially backing out. Those three were stripped of parts and destroyed as correcting the problem costs more than a new gun.
Would not mind having one or two or one of each myself. The 340 is a nice piece and I would not mind being able to pick one up in 30-30. Anyone know the availability of 340's at the gun shows? Never see any on the used rack.
