Not Northern Dave but I would guess he wants any possible condensation from the rifle going real cold to warm to dry quickly....
Egg-Zackery!!
that damn hot-cold-hot-cold is a bugger. I like to let the air move through everything things can dry as or shortly after condensation builds from coming in from the cold.
we warmed up here, balmy -13 this morning before i left for work.
Thanks.
