Check out the Kankakee gun show for primers. I bought Win. 209's for 27. To really cut costs on your 12 ga. reloads go for a 7/8th or a 1 oz. load. I can reload WWAA for $4 a box with 1 1/8th oz of shot. But it is something I enjoy to do no matter what the Estates sell for, a hobby within a hobby.
Blackpowder shotgun shell reloading...I thought I was the only one! And you shoot at Des Plaines too!
