Right now you can get a NEF ultra slug gun and use
4759 loads in plastic and brass 3" cases. You can get
a Savage 210 and rebarrel like I did. And put in
long chamber. Use 4759 3" loads in it also and
many other modern 12ga shotguns.We are scaling up
a falling block hopefully to be produced in the future to
use, at a decent price.Ed
