has any body tried buying 24 gauge empty plastic shot hulls lately? they seem to be as rare as rocking horse droppings. I use them in my .577 SNIDER be cause they are a whole lot less expensive than the 24 gauge brass shells. but no one has them. I used to get them from BALLISTIC PRODUCTS for $15 a hundred primed. no more. I guess every one has horded them? any else had a hard time finding them?
