I don't know how to prevent it, nor do I claim to
know exactly what causes it. That being said,

I think we should file this under cold weather,
or maybe old "wives" tales. Or maybe the human
species, of the hunting people, that is, just plain
don't like the "whammy" being aptly applied to the
shoulder or cheek area in cold weather. Well I
don't know about you but I sure confused myself!
Good shooting & God Bless.....Danny
