I think you are getting old if you think you will be able to purchase at 3¢/round again. That's like coffee for 25¢ per cup.
I see Sportsman's Warehouse has a number of bricks of .22 (Thunderbolt) ammo for $24, which is about $.05/round. I've been hearing .22 ammo is becoming more available lately - is that the going rate these days? I'd like to find it for about $.03/round. What are my chances?
I just went by there and they said they haven't had any since earlier in the week.
