good afternoon all where can I buy 24 ga plastic shotgun shells at ? trying to reload them for old 577 snider so as of today none around found one company got last ones in a year ago thanks for any help you can give me ... bill oh if I did try out brass shells and reload them would they have to be resized ? I have a 450-577 empty that was fired and it fit very nice into the snider again thanks for your help
