The supply of ammo will reach an equilibrium again, just as it always does.
One thing that has truly been missed in this latest turbulence is the debt of gratitude we all owe to Walmart. By not jacking up their prices on ammo they have prevented an almost certain permanent inflation in ammo prices. We will see if their downward price pressure can stem the tide.
I am not a pro or anti-Walmart guy, but shooting enthusiasts should give credit where credit is due. They have earned my business for ammo and I have lots of friends who feel the same way.
