I collect the Marlin 336 model SC's and have a few in 35 Remington. The SC has the Ballard rifling versus microgroove. The one you're looking at just might be pre microgroove. One of them I have, I have used in old style lever action rifle matches and it's a near one hole shooter at 100 yds- a very accurate shooter. All of the others will shoot under an inch with the right handloads. Despite what you might hear, they will shoot the heavy bullets of 250grs- at least all of my SCs will. As far as price, because I already have all of the chamberings and am just looking for something better than what I have, I don't give much for one. I'd suggest checking at Auction Arms and see what they are SELLING for, not what some of the fools out there are asking. There will be different models and that's important in the pricing so find out which one it is. The SC's have been bringing more money. SC means Sporting Carbine and is the short tube carbine version of the Marlin. The pre 64 should have a walnut stock on it, not a white birch stock stained walnut.
