shot a deer(first one) keep it.......every time you shoot it you'll remember, my first deer was with a bow I still got it...

I love my 512. Does yours have a wood or synthetic stock? I'm thinking wood if you say the gun is heavy. If synthetic I may be interested.

The market for 512s is pretty good. It will sell quickly if it's in good shape.

I don't know why you have a problem with the scope mount. Mine is fine with a Bushnell 1.5-4.5 variable. The easy answer is to shorten the stock a bit. This will help with the forward-positioned bolt handle too.

I guess the only way I'd sell it is if you really need the money to buy the next gun.

I know how you feel... its a tough call. I own my 2 great-grandfathers shotguns. One is an old single shot and has his last hunting liscense in the stock and the other is an old modle 19 marlin thats unfireable and can never be made so......and I'd never sell either one

If you can get a good price for it then sell it and get the Savage 20 gauge.
Wait to purchase a tree stand until after you get the new gun.
