While I see the good in sitting on stuff, I also see the good in letting it go.
I like to buy, trade, barter, and sell. I do it so that I can continue to shoot and enjoy our sport, no matter when the time. I’m pretty well set up with stuff, there’s no doubt; however, when I buy a new to me caliber (e.g. 204 Ruger) and can’t find any components on my shelf since I have no other cartridges in that caliber, I have limited choice. I can pay inflated prices, I can wait to shoot until things come back, I can barter / trade with someone to get something we each need, or I can sell something to cover the costs of what it’ll take for me to get what I need.
They all have a time and they all have a place. I also agree with helping out other loaders. The amount of stuff that I’ve been blessed with over the years from people giving me, is countless. I try to do the same for others.
If I were in your shoes, and had components or equipment that haven’t been touched in years, this is what I would do:
1) Try to barter / trade your stuff for items you do need. Find a website (Graf’s, Midway, Powder Valley, etc.) and agree to use the prices from there to determine trade fairness.
2) If you can’t manage a trade, sell it off to get the stuff you need. Deciding on the price is up to you. I often do a WTB first to see what it’ll cost me, and then sell stuff to cover the dollars.
3) If your covered and don’t need the supplies, sell it reasonably to those who are looking or give it to shooters who may be in need. I realize that we are in a crazy market right now, but if you’ve had supplies you haven’t touched in years, are you really going to touch them before things come back? If not, part with them. They aren’t helping you, but could definitely help others.
