Cold weather shooting considerations article recommends to put masking tape over the muzzle, or use a condom secured with a rubber band to keep snow out of the bore. Does anyone use this trick? If so, do you always remove the tape/condom before shooting? If not and you shoot through it, how does it affect accuracy? I'd rather not test it at the range, as peppering fellow shooters in lanes next to mine with condom fragments does not sound like a good idea.
