Hey, I have a Marlin 30-30 and LOVE IT!!

It had a small Glenfield 4x32 scope on it, but it broke on me last season, so I took it off. Shooting a "plain jane" 30-30 with open sights seems to be a little better and easier to carry. I just might keep it without a scope... I too don't shoot over 100 yards.
P.S. The 30-30 is a timeless classic that has killed more deer than any other rifle in any type of caliber. Grab one andenjoy shooting a real part of hunting history!
