For those who shoot unusual calibers...
Probably a good time to stock up. Some items still available, but wonder for how long. Manufactures gravitate towards profit only. So, the more obscure stuff will be the last to go back into production.
I stocked up on 38-40, 10mm Magnum,41 Special and 44-40 brass before it's gone.
Many calibers have never returned after the last shortage. I suspect this shortage will last a while. The more obscure stuff will definitely take a back seat to the stuff in high demand.
