I considered the condensation aspect and really don't know what to do other than try not to go instantly from warm house to cold vehicle trunk, or vice-versa. Not sure how best to "acclimate" my equipment, though. I was more curious about how the ammunition would react to the temperature changes.
If you bring your cases along, or at least leave one outside at the house, so its at the ambient outside temps, just put the gun in and close it before you go in. Let the case sit and come to room temps, and you wont have any condensation problems.
Temperature doesnt really affect the ammo all that much, but there are usually some changes in velocity. Heat up, cold down. Shoot all year round and keep track. Thats about the only way youre going to know.
While focusing on the shoot in this discussion do not forget ice cleats if there has been ANY rain/snow recently. Can't shoot from the range bench or check targets if you cannot walk straight
to them!
Strange, water freezes on the firing line. Right under the shooting tables
Our club only plows the road in, and doesnt do anything else. Even then, sometimes its a bit hairy even getting in.
Ive shot in 12"-18" of snow in snowshoes more than a few times, with both rifle and handgun. Fun stuff actually, and good experience.
I think the biggest thing is being properly dressed to be outdoors, and staying comfortable. Ive worked (and played) outdoors year round most of my life, and I just dress like Im going to work. Dress in light layers with a 1/4 or full zip hooded fleece under a hooded windproof on top. On the colder days, I wear a pair of Carhart bibs too. Proper boots for the temps, and mittens for your hands.
I like mittens because they are warm. Warmer than anything else. They are a bit of a PITA until you get used to them, but youll also get used to having warm hands pretty quick too.
Another advantage is, you can drop one of the heat pacs in each one, and youre really toasty for the day. Almost to toasty sometimes, but its great if your going to have your hands out a lot.
I just shake the mitts off when I need my hands, and always have full feel and dexterity that way too. If my hands get cold, I just pop them back in for a little while.
And, like anything else, your attitude and mood can have a lot to do with things, and go a long way in making things go better. If you convince yourself youre cold, its going to be a long, miserable day.
