I recently installed a scope on my 1967 F chambered in .358 Winchester. Prior to that I had a Lyman 57SB and was getting 2" groups, plenty good enough for deer at woods ranges. My main concern is the first shot from a cold barrel, but I'm wondering what others have experienced with the F in .358 in regard to accuracy and group size. Right now I'm not doing much better than 1.5" with three shots.
