I've done it before but that was a long time ago. I could do it again but see no need to. I enjoy the ones I own. This is a hobby for me and I think a good one. They don't cost anything while not in use, once cleaned they are basicly maintenance and hassle free. They will always have value and are somewhat like money in the bank. I don't have a whole lot but like the ones I own. I'll thin the heard done one day as my hunting and shooting decreases but hopefully it won't be anytime soon.
