I don't have a gradual warm up opportunity since I'm frequently coming from the stand to the house, but I've never seen condensation on the outside of the gun. Then, I might be coming from +20 degrees into the house, but that's about as cold as is likely. What has tipped me off is when I pull a bullet, almost no powder falls from the barrel when turned upside down. I have to send a ramrod down with puller to break up the powder, several times, before most of it will pour out. There's just enough mositure to form a slight crust which I suspect is more difficult to ignite, almost like a pellet. So, now do you think Goex would solve that under the Pyrodex?
