They will be expensive and take a while to replace right now because most of the suppliers are backed up. If you can reload them, I'd hang on to them. You might be able to quickly and easily replace them in a month... or six... or two years... or.... who knows.
I vote to hang on to them if you have something to use them in, never know when you would be able to replace them and more than likely at a higher price.
In my humble opinion... I would load and shoot them. If you have a gun in that caliber why not? Just because I don’t know when you can replenish your inventory.
I had a friend give me a bag with at least 500 double ended wad cutters fir 38 spl. Tried to talk him out of it but he did not load or shoot a gun chambered in 38 spl. I have loaded about half of them and shot about 100 so far. Will load the rest and put them in inventory
