I probably wouldn't do it either. What do you have in your 597? A buddy sold a 710 in .270 with a nicer Simmons scope on it for $250. Well, that's what he was asking. I don't know what he got. I thought even that was high. The 710's aren't known for being great rifles although better than the 770's. I wouldn't do it because you could either keep or sell your .22 then go buy a nice Marlin XL-7 for around $300 from what I've read which is a much much nicer gun. You can also get a Savage package deal for not that much more which is also a lot nicer.
