I have a 1920's vintage Belgian 12bore A5 with 29" barrel; it's my favorite trap gun, because it's the only one where I've shot more than 50 straight.

I also have a 1930's vintage Remington Sportsman 11 in 20bore for the kids.

The A5 was an amazing technological achievement and can do things that modern auto loaders just can't do. The A5 is the invention that Browning was most proud of; rightfully so if you ask me.
