I think it depends on what your overall attitude is toward the 12ga Tracker II! Does the possibility exist that you make go back to it later?
If you think you will never shoot it again, then rather than hang onto it, sell it to someone who will use it! As to the ammo, you could list it for sale, here or on an auction site.....it is legal to ship personal use ammo via UPS ground IF the pkg is properly labelled.
I went the opposite direction....I had an H&R USH in 12ga. I got one deer with it, but decided that it was too heavy for me for other than stand hunting. A lot of what I have found myself doing is "still hunting" or stalking through heavy cover, especially on those windy Nov-Dec. days. So...I went to the Tracker II.....
I also found the recoil to be astounding. I did 3 things: 1. I had the barrel ported to reduce muzzle jump, and keep the forend in my hand; 2. I added a mercury recoil reducer to the stock; 3. I found a 2 3/4" 1oz. sabot slug that is quite accurate out to 100yds, has plenty of knockdown power, yet is tolerable to shoot more than 5 rounds at the range with modifications #1 & 2.
Every once in a while, I find myself wishing I still had a gun that I sold, and sometimes wind up buying another one!
