Ouch.... no my experiments were with a Remington Inline...

The key for me is not to warm up the barrel to fast if you see condensation forming on the out side then it is probably forming on the inside. When we come in from hunting, even in 20 below weather the gun, either inline or sidehammer goes in the truck with for the drive home. But, the truck cab is 20 below also or there about, then as we drive the gun warms slowly (never really heat the cab up - just take the chill off) - from the truck it comes in and stands in the back room. I take all waether protection off and 1/2 cock the hammer - then the gun can breath... The other thing with sidelocks I have given up on 2f powder @ 20 below and using a cap it is hard to get T7 started. So we now use T7-3f and we take a lot of care in pouring in just a bit then tapping it over under the nipple - the 3f moves over really easy, the 2f not so easy... We have found out if we have a dead air space between the nipple and the main charge (other words) the flash channel we do not always get a positive ignition in really cold weather, warmer weather 25 and above above the 2f works pretty good.
