Dan's picture reminded me of this. I do not recall anyone having trouble with ignition.
All but 2 were shooting flinters. Steady dusting of fine snow.
Temp of the day and that of the firearm is the key and care by the shooter. If the rifle is COLD enough and its below freezing the snow is not really an issue. But shooting warms it up. Hunting many times where I live even with snow the temp can be around freezing. +- and if having to lay the rifle down or stand it under a snow laden tree? It has to be in a case. The only time I wetted a Fl I had shot two deer a couple of minutes apart and laid the reloaded rifle on the last one a little carelessly, and the pan touched the snow and got REALLY wet real fast. But I had left the cover in the pickup because this was a fast hunt, the rifle was cold and I was not worried about the stalk and shooting in creek bottom brush. Had I had a cover with me it would have saved me some trouble. There is a beaded cover shown with the Dickert Rifle in the first Moravian book and the English trade rifles that came into Canada during our revolution came with canvas (IIRC) covers. I never could figure how a cows knee was supposed be very effective.
