Got a Stevens 200 SA and am thinking about putting it on a diet to make a lightweight 7/08 and would like your input. I'm thinking about keeping the tupperware stock and going with a 21" thin barrel. Anyone got any idea what this combo would weigh? Do you think I could get anywhere near the 5.5# that the new model 11 lightweight hunter is supposed to weigh? Any suggestions on make and contour of barrel would be appreciated. Not looking for a target rifle but hope to keep accuracy respectable.
