I'm down to about 70 from about 120. (If you include handguns)
The one's I have and obtain tend to be more expensive and I'm more selective. If it's not better than one I have I'm not usually a buyer unless it is rare, or a great deal.
Having raised three sons, I always felt like I needed four of everything to handle our outings. Four duck guns, four trap guns, four deer rifles, four slug guns etc....
At some point though it's hard to justify four graded Fox 16's just so you and your sons can go grouse hunting. I've really enjoyed selling small bore Field grade LC's and Fox's to friends just starting to appreciate the better handling qualities of classic side by sides. It took me years to find some of them so it can be hard to let them go but in the end they will get used and appreciated instead of just sitting in the back of one of my safes.
