That's good info/news to me.

One of the slickest 870s I know was one used by a duck hunter who put that gun thru years of abuse/use that only made it all the smoother. Read an article years ago by another guy, shot competitive trap as I recall, he had shot his untold tens of thousands of rounds. Seems you cannot wear one out....

A semi does have a slight speed advantage in the field, but it's only an advantage if you do not waste subsequent shots.

Many years back, my Dad used Model 12s extensively over the years, and later went to Browning and Beretta about the time steel shot was mandated and for recoil reduction. His M12s had nice Bishop/Fajen wood he checkered himself and finished by hand rubbed oil - and nice blue. They served him well for trap when not using a his base model Krieghoff.

For my use, a shotgun is a great tool, so I can take an ugly stock wood or synthetic, just sans the high gloss wood to not spook game. The satin wood stocks today are fine and matte blue has it's purpose.

Thanks for the info on the tubes, great to know.
