RE: Sentimental about gun?
Personally, I wouldn't sell it. I'd look into getting the feed problem fixed, and maybe find out if the accuracy can be helped at all.
If it is a lost cause, I'd still probably keep it. I'd hang it on the wall if it's good enough to look at. You might check the books to find out if you can fill the bbl or chamber with caulk or something and remove the firing pin and hammer (render it inoperable) and legally hang it on the wall. If not, I'd probably still hang it on the wall, just take it down when cops or gov't officials come over for supper.
You might look at how much you really feel for the gun. I pretty much know in an instant if I can sell a gun. If someone asks me if I'd sell one, my first instinct is typically what I'd decide on after a year of pondering (and I've had that happen in the past several times!!!). The way you're asking, you're kind of wanting us to convince you to go ahead and sell it, meaning you've already decided you don't want it, but if someone would say "don't sell it or you're regret it", you'd think harder about hanging on.
I have no problems selling guns I don't "love", but there's no amount of money that could buy the guns I do care about, even if they aren't worth anything. For example, my father gave me his old .410 single shot, which was his dad's before him for a little while. It's not exactly an heirloom, just that it's a gun that works and he needed a gun so his dad gave it to him, and when I needed a shotgun, he gave to me...It's about 5% finish, the hammer spur is broken off, the fore-end has a sliver broken off and the retaining piece is missing. The butt plate is missing (actually more broken than mounting it is worth). The stock is cracked terribly and in several layers, it's been roughly wood glued and was even held together (still obvious) with a hose clamp. I could buy a new equivalent gun for $80, and I do have a new H&R/NEF that's very similar to it....I also bought all of the replacement parts I could to "repair" that gun, but I've not yet installed them.
In the condition it is in, the forend can't be mounted, so you have to hang on tight when you open it to load it, otherwise it falls apart! I've developed such a relationship with this gun that I spent $200 on those parts that I can't bring myself to put on, and I take it afield falling apart every winter, holding this UGLY gun when I'm known for being an "avid shooter and gunsman". But, I take more game with it, and have more fun with it than any other gun I've owned. I baby it like it was made of solid gold, even though it's been recovered from the bottom of a creek a time or two, and dropped off the back of a truck on the highway.
I'll put it this way, my fiance once asked me what I loved more, my guns or her, I said I loved her more, and she asked, "so you'd give up all your guns if I said I'd leave you if you didn't," I said I'd let her walk out if she made me give up that .410!!! It's a turd that's barely functional, and I've certainly got several guns that of the same "type" that are in better condition, but that one is MY GUN, not just one of the guns I own.
