I have been noticing headaches when hunting ducks. Lots of 3 inch and 3.5 inch 12 ga is, I think, starting to take its toll on me. (we have lots of ducks up here and I miss a lot!
) Would love to knwo where to read up on this or how it is diagnosed. Might have to give up the big shot payloads and get more patient about letting the ducks come in closer or not shoot at them. Good thread, I will be watching this as I am pretty sure I am now a victim.
