Calnubie, good thought!!!!!

Here's another idea.....find a primed case.....no powder and no bullet.....primed case only and take the gun indoors and wait 24 hours to warm up. Install the primed case and point in a place to muffle the sound and see if you can fire the primed case. I've seen Sakos that have so little clearance between the firing pin and the firing pin hole that the hole closes up in cold weather and don't let the firing pin through!!!
