Thanks Daryl for starting a separate thread focused on modern live bird shooting. I don't own a suitable 12-gauge Parker but I'll offer this up ….. to be competitive and not waste your money in a very expensive sport where still legal, I think that Parker needs to be dynamic but with enough weight to buffer heavy recoil, perhaps around 8 pounds. Also it should shoot a bit high maybe 60/40, and its owner must be OK with sustained shooting of traditional 1-1/4 ounce high velocity pigeon loads like the old AA Super Pigeon without having to worry about being kind to old dry wood, etc. Nowadays many shooters will be using even higher velocity "high brass" 1-1/4 ounce loads (1330 fps) in their guns. I'm talking here about getting invited to organized live box bird shoots with high cost birds, high stakes and the Calcuttas. And even if you have that Parker and think you're a good clays/hunting shot, get ready to get your clock cleaned when regular pigeon shooting gents like "Lxxx" show up from Portugal etc.
