i agree there are probably a lot of stories on here.
My best luck shot was one morning out duck hunting with my dad, he always used a pump action 12gauge and i only used a single shot .20ga. we had a bolt action .20ga. that held 3 shells but honestly it was too dang heavy to want to carry all day.(still have the gun but someone lost the bolt and magazine) Anyhow out hunting one morning a few ducks flew right towards us and as i raised the single shot to my shoulder and took aim all i heard was him saying them birds are too high up.
Boom, duck fell right at our feet, all i could do was say "Too High huh?"
