Has my interest waned? Most definately!
I used to go to a range that was free and you shoot almost anything. Then one day I go there to find it "formalized" to where there is now a rangemaster wanting a $5 "donation" to tell you that you're only allowed to shoot NRA certified paper targets. Your own paper targets aren't good enough. Water jugs, pop cans, or anything else is banned. Oh, and to shoot pistols, the minimum is 50 feet. Shotguns can only be fired at flying clay disks. No tactical shooting at all.
Then I try another range that only lets you shoot rifles, and only from 100 to 600 yards (at the ranges own paper target only), and only at the distance the majority of other shooters there agree upon. .22 rifle at over 100 yards is not allowed. Shotgun slugs not allowed. Handguns not allowed. Can only shoot 1 shot at a time while a target operator marks each hit on the target afterwards. Is shooting in such a strict and regulated way like this supposed to be fun? (I went there on a day it was agreed they'd be shooting at 100 yards. I brought my .22 and drove out there only to be told that the other people agreed at the last minute to shoot at 200 yards. So I didn't get to shoot at all.)
All this, along with the increased cost and unavailabilty of ammo doesn't make the hobby much fun anymore for me. So now, I try to look at my guns in a practical way:
What are they for? Mostly self-protection against home invaders and the possibility of complete economic and national collapse. I feel safer having them because they give me the ability to defend myself. As a result, I don't need very many. I figure 2 or 3 handguns, a .22 rifle, a shotgun and an AR. If the AR became too much of a "pain" to have, I'd have a second shotgun in its place. Altogether, that comes out to about 6 guns. With those, I feel I have what I need in a practical way. I feel I have what I need, which makes me feel good in that way. As for wants, I can fulfill those with other hobbies now that the fun has been taken out of the gun hobby.
