The wood on the stocks is much nicer on the 336c models. One has a walnut finish, the other is a walnut stock. Other than that, they are going to be the same guns mechanically.
If your only going to be shooting at 80 yds or so, ditch the scope. You might be surprised when looking at the open sights that come on these guns, and want to keep them.
I have 3, 336's two in .35 Rem,one is a sc from the 40's and one is a cs from the 80's, and one in .32 Win Spec it is an a from the 50's. All of them have very nice sights, and I only use the open sights that came on the guns. The two from the 40's and 50's have much nicer stocks than the one from the 80's, but I think that c's now have pretty good wood.
Anyway, which ever one you choose to go with I am sure you won't be disappointed. FYI, I didn't give over 200 for any of mine.
