I've been duck hunting for about 12 years now and never killed a canvas . Killed alot of hoods though. Had a buddy first year duck hunter killed a redhead bout month ago. I've never got to work a canvas or redhead, it would be going on the wall for sure if it was me. Good job on the ducks! I'm no pro by any means but you can pm me I'd be more than willing to talk ducks w ya.
