I got a Winchester model 69A target model in 22 lr and with the original Lyman aperture sights from an estate recently. The rifle is in good shape though there is a tiny patch of rust on the magazine which I could take off with some sandpaper. I already have a nice and cheap but very accurate Marlin model 60 in 22 lr and I am wondering if I should rebarrel the Winchester to 17 HM2 or keep the same barrel etc and just get the rifle reblued and the stock refinished. Some friends have been telling me that the target model is somewhat rare and that I should not alter anything on it but I saw two regular models (not target) on sale at Cabelas, so these things can't be all that rare.

I would appreciate any advice on this from experienced members here. Thanks in advance and good hunting!
