WOW .... I can't believe I missed this post for so long.

I collect these ... and ... I've been shooting them for years ... I'm still looking for a 20ga if any of you hear of one for sale. Here are mine - along with a Browning Auto for size comparison.

I even had a custom bullet made for the 16ga's .... I use it "as cast" in the 16ga ... and size it down for the 18ga. I also had 120 18ga brass shells custom made just so I could shoot that one.

I've even got extra brass if someone needs to load for his 18ga.

Here are some of the different calibers (gauges) offered for them.

And here is an assortment of "Bird" targets that are used for these events.
