Winterizing my PCP’s😆

Last year I put mine away for the winter, and all I did was lower the pressure to below reg set pressure to ease the stress on the reg, then tape on the gauge at the point I lowered it to see if it lost any air over time. Then cleaned the barrel and ballistol all the dirt and finger prints off the outside. They looked brand new in the spring, and didn’t lose a ounce of pressure. 

I have mine full charged up here in ND, heck I will take them out when it is well below 0 with wind. The only thing to watch is the pressure difference. The colder the air the lower your pressure will be. So if you fill while the gun is room temperature and then go out into below freezing Temps, the pressure in your gun will fall.

As well as if you fill the gun while cold to full psi, and then take inside...you could very well have some issues with over pressure

Something I have wondered if would apply to our airguns. I have worked on high pressure pneumatic circuit breakers that are in substations. Several times over the years I have been on a trouble call because of an air leak that was caused by o-rings becoming hard from the extreme cold. What would happen is the cabinet heaters or heaters located in an enclosure was not coming on. There were times we could heat the area where the leak was and the leak would stop. We would fix the heater and plan an outage that wouldn't affect the grid.

I live in Arizona my rifles are inside climate controlled area and I am a fair weather air gunner. But wonder if you took a gun in extreme temperatures would a leak develop like I explained above? 

I live in Southwest Pennsylvania also.Not far west. Not too far from Maryland and West Virginia border. I still take mine out on the porch now and then and shoot them a little bit in the winter. I usually keep mine Stored halfway On the gauge If any of them are going to be stored for a significant amount of time.I just wipe them down with a lightly oiled rag and some of them are in cases. Don’t clean my barrels if they were shooting accurately before hand. House is dry in the winter and don’t have to worry about rust.

Just like you car/ truck tires, be sure to change the summer air to winter air!!! LOL..

lol - life's too short, just shoot it and have fun

Using caveman logic: My normal practice is to regularly dry shoot my guns pointing up wards several times before my shooting session. if planning to store them (rare for me), set them barrel up for several minutes, then dry fire several times. The logic is that any water build up will flow to the out put of the air cylinder and will cycle out of the gun during dry shooting, thereby purging your system of moisture.

In Texas, I had a bit of the opposite issue yesterday. It was still warm and I left my gun in the case in my truck all day. When I pulled it out, the tank pressure was fine, but the reg pressure was a few hundred pounds higher than normal. I dry fired and the gun returned to it's normal reg pressure.



I imagine the opposite would be true in cold weather, the only question is whether or not that *could* *possibly* damage the regulator or something, but I'm assuming these guns are built to withstand a certain amount of temperature change.
