My son has an 03 that is a Smith Corona 2 groove barrel. The old gun has been sporterized at some time by a pretty good smith and we both like the gun very much. Alltho the barrel is badly pitted it will shoot a 2 in group at 100yd. Our local smith has quoted us a price of $175 for a fully installed Adams & Bennett barrel in 06 , 308 or 25-06. The price dosen't seem bad considering the work to be done but do you guys think we would see enough improvement in accuracy to make it worthwhile. Also which caliber would you recomend as any of the three will take a deer at the ranges we would be shooting. Thanks for any input. olredhead
