I go through "phases".....
When I was in my 20's, I collected military surplus bolt action rifles, and had over 100 of them. I had tons of fun shooting surplus ammo, but interests change and sometimes you need to pursue new chalenges.
I sold them , mostly all off, and used some of that money to begin to accumulate Ruger and S&W revolvers. I sold off many of the S&W's, and kept the "cream" of the Rugers. Handguns were just more convenient, more fun, easier to store and it was easier to set up at 25-50 yards than 100 and keep walking around back and forth at the range. Shooting became less of a driving force in my life and more of an actual hobby that I enjoy when I have time. I am perfectly content to hit the gun club, staple up a 15 yard target, shoot a box of .38, a 100 rounds of .22 and go hit Taco Bell to go home for movie and chill time. Going to the range used to be an all day event, 1-2x a week for me. Now I can't imagine spending that much time there. I have recently popped over to the gun club to shoot 1 box of 9mm and I was fine with that.
I also enjoy shooting blackpowder firearms such as percussion revolvers and military rifle-muskets. For the past year I have fired nearly nothing but percussion revolvers and muzzleloading rifles. I have gravitated back to Ruger revolvers, mainly single actions but I don't know where my next "swing" will take me.
So I am really not buying a lot more, and not selling any because my Ruger revolvers have sat unused for nearly 4 years, and I'm finally coming back to them . So I am thankful I didn't sell them all off because I "wasn't using them" because it would suck to want to shoot something and remember that you sold it off, and the replacement cost is now too high . Because you never know what you'll be in the mood for 2 years down the road.
I'm holding what I have and people in my family can worry about it when I'm dead, if they want to hock them, I hope they'll be smart enough to get market value , whatever it may be then. It's basically a Trust Fund. Some of the guns I bought because I thought they looked cool like my .41 Bisley Blackhawk are worrth 3x what I paid. I never worried about it because I buy them to shoot.
