These CNC machined aluminum shotshell dummies from Advance Ratio Sports and Tactical will make you a better shotgun loader. All the other shotshell loading dummies I've seen eventually wear out because of the plastic body. These dummies are machined from a single piece of aluminum and will never wear out. Each shell weighs 1.9 oz. Comes in a package of 4 for 12 gauge only. Price is $21.95.
