This thread really makes me feel warm and fuzzy inside. I thought I was the only one with these sort of feelings on selling things. Heck, the last three I've sold are a distant memory already....maybe I don't have as much of a problem as I thought! LOL
224 Valkyrie AR- It was a great rifle. It shot tiny little groups all the way out to 750 yds, but I didn't enjoy the hassle of having to deal with chasing the brass, and the unavailability of decent aftermarket brass made me sell it.
T/C Encore Prohunter Muzzleloader- great rifle, shot well and harvested many good deer. I wanted to build a smokeless rig, which I did, and while I didn't 'need' the money, my conscience told me that I need to sell something, so I did.
460 S&W Performance Center Hunting Pistol- this was an impulse purchase in the first place, and it just was not enjoyable to shoot. The macho factor was was really high on it, but so was the value, so I sold it to a friend that really really liked it.
