I know some said that German guns were often 3/4-full or fuller-fuller because Fritzie hunted them "chicken sized turkeys" from tree branches deep in the woods or shot bird by removing slinged gun from shoulder (many old German guns have sling swivels) before shooting therefore needing longer reach. I always thought they choked guns that way so we could open the chokes to our own liking. wink
As I stated previously some of the most practical guns were made by people from cultures with little upland hunting experience. Recently examined SKB Royal Light1/4-full choke combo underscores this notion.
