Maybe my eyes are getting worse or I simply suck at marking a downed bird but I've lost 4 Dove this year while hunting and I know they were all shot DOA in the air. Watched the birds fall and either marked with my hand or picked out a plant stem to to mark the spot. The last bird I hit yesterday I marked with my hand and walked right over and even found the dang WAD from the shotgun shell and I know it was my PT-28 Remington wad from reloads, even had some copper plate dust on the inside to confirm it was my spent power piston. ( How can a man find the wad but not the dead bird in the grass. At this rate I might have to teach a house cat to retrieve birds, can't afford any more pets lol have to make use of the one I have.
