I used wool Jeff,w/thinsulate in finger less mittens with a flip-over end that covered the fingers. I also used a pair of thick snowmobile mittens with long cuffs, but the right one was too hard to get off quickly to take a shot. That's when I changed to the wool ones with flip-over ends. Much easier and my hand didn't freeze to the stock. In those circumstances, only the first shot
was a patched round ball. All the rest were ctgs. that could be loaded without taking the end cup off the mittens.
I don't do that STUFF any more. Thinking back on those days, I really can't imagine it but, well, that's what we had to do, so we did it.
