Bridged shot? I understand that is usually an issue with larger shot, but is it more likely to happen with 7.5s in a smaller bore like a .410, where that shot size is proportionally larger to the bore than in a 12 gauge?

Hope you ate it quick - otherwise, it might become Ichabod Dove, and will return headless to haunt you every dove season eek

Such a long, long time to be gone, and a short time to be there.
