Firearms
No article on prepping would be complete without some discussion on firearms, and using them in winter conditions can present some unique challenges. Firearms are precision machines made from metals and polymers, and cold weather can have some big impacts. The materials themselves can become brittle at extremely low temperatures, so you should avoid sudden sharp impacts if possible. Shooting a firearm can heat up the barrel and other parts pretty quickly and cold temperatures can cool them back down rapidly, which can cause weaknesses in the materials, so you should start off with a slower rate of fire if possible so it warms up more slowly.
The more complex the firearm the more likely it is that it will be impacted by winter conditions. Break-action and bolt-action guns are pretty simple and tend to be reliable under any conditions; lever-action and pump-action guns are slightly more complex but tend to be relatively easy to clear if a problem does occur. Semi-automatic and automatic firearms are precision instruments with tight tolerances, and are the most likely to be impacted by winter conditions. Revolvers tend to be a unique case – I’ve talked to some people that have never had a problem with them in winter conditions, and others that have had jams and freeze-ups frequently. Whatever you plan on using, make sure you practice all aspects of firing and manipulation in cold, wet and snowy conditions.
Any liquid including lubricants can freeze up in a firearm and cause problems. Many common lubricants start to gum up around 0°F, which can cause jams and other malfunctions. You should ensure that every part of your weapon is dry of lubricant by disassembling it and wiping it down before using it in winter conditions, and switch to a low-temperature lubricant like Moly Coat, Slip 2000 or Break Free CLP in the winter. Water can also cause problems, especially with fine blowing snow that can get into everything and melt, then freeze up.
There’s a phenomenon known as ‘spindrift’ snow that consists of very fine snow particles being blown around by wind vortices, and it can get into the tiniest cracks. You should seal up any openings on your firearms including closing dust and optics covers, and cover the end of the barrel using a condom or electrical tape. Don’t forget to cover any openings in muzzle brakes, flash suppressors, etc. as well as the end or the barrel. A note from a friend of mine on using condoms – if you plan on using them to cover the end of your barrel, make sure you tell your spouse about them before they find them in your stash.Continue reading“Cold Weather Considerations – Part 6, by JM”
