I started reloading back in the mid 1960's for my ever changing collection of 19th century rabbit eared doubles with black powder and a Lee Loader. Fiber wads and paper hulls were the norm and chamber length... what do mean chamber length?
My shooters have evolved from Belgian clunkers to my current novelty of 1920's-30's "Hardware Store" guns, ie: Crescent, Davis, Stevens, etc...
Black powder goes in the .45/70 and muzzleloaders.
As for the Davis I have an old magazine ad that claims it "Kills Ducks at 80 Yards".
As a occasional trap shooter I have to be having a really good day (which I actually do on very rare occasions) I turn in a decent score.
Super long forcing cones and extended choke tubes! Hmmmmm...
