Owned many, sold some, traded one or two and gave one as a gift.
Two rifles I regret selling:
1) Reminton 700 Mountain Rifle in .270 Win. Bought it used, looked like new. Spent a small fortune on it's customization. McMillan lightweight stock, trigger job to 3 crisp lbs, recut crown to 11*, bedded, everything lapped and mounted a Leupold VXII 3 x 9 on it. Handloaded for it 'til I consistantly shot 3 shot groups at 1/2" with 140 grain bal tips. Thought I wanted a "bigger gun" after two years with that .270, so I sold it to a sherriff's officer aquaintance of mine. That was 14yrs ago. He still won't sell it back! Says it's a tack driver and kills all his deer. He always says "no way". Maybe I can get him drunk one day and buy it back!!!
2) Remington 700 Classic in .35 Whelen. Again, spent a small fortune on the customizing job as on the .270. Only difference was a Bell & Carlson stock. This rifle shot at 1" with two 200 grain handloads and 1.3" with 225's. Killed some nice critters with this gun. Had offers to buy after people saw it shoot. I said" I'll never sell this baby!" Yeah well, I eventually sold it for financial reasons and regret it ever since. Truly wish I had the Whelen back.... Oh well, there's always another classic out there somewhere that needs fixin'!!!
