How cold is too cold to go out with our PCPs

I have worried about the same thing a lot, but yesterday I got a squirrel and a porcupine and the tuck said it was -17. Used my .22 pp700 and was not problems at all. I was going to try coyote hunting this week with my rti prophet but just don't feel like sitting in the cold that long, of course when I go back to work we will be warming up into the 20's. Hopefully my next days off I can get out some. Also need to add we weren't out for more than 30 min at a time then going back to the truck to warm up. I also topped off the pp700 when we got back to the truck with it being out in the cold, It does drop pressure a lot with the cold.

I hunt in below 0 weather quite often. Only trouble I have is the lubricating oils my freeze up. I use powder lubes in the winter. I also leave my rifle outside durning deer season to keep it the same temp. Otherwise when you bring it back in to the house, you have to clean it real good. Condensation will make the rifle look like it just took a bath. Plus you will loose a few shots do to loosing some pressure. 

Hunting? Whatever you can stand. Shooting in general? Should be okay.

Shooting tethered with E grade air through a step down in-line reg in super cold weather will guaranteed freeze your reg up or bleeder, or anywhere else compressed cold air is released & becomes colder. 
That is the only problem besides fogged scope from fast temp change. Moisture will freeze & build up at fittings usually. That was 13*F last my reg was leaking with ice build up at bleeder.

Test it for accuracy.

I shot in 116 deg F weather and the only rifle that could shoot decently was the BSA R10

If you're cold, they're cold, bring them in. (Sorry, couldn't resist using that line.) I kinda of baby my guns all the time and do the same in the winter. Dry lubes only for sure.

Hi -10 huntin pheasants with a pbba 20 ga only good for 2 shots and the setters only out for no more than 2 hrs!? uragan 30 still same poi@ 100 only first 5 shots . just warm gun up dry off and i relube. paperp

Uncle Bill would always say:
"if it's cold out, put it back in"

I was interested in this same subject, so I took my regular shooter (a very highly modified 2240 with a 450cc bottle) out yesterday when the temp was 12F and put my FX Chronograph on it. I took it out of my office, that was about 65F and started shooting. It performed like it always had for the first 15 or so shots, with a spread of about 8-10FPS, and then my spread went WAY up! I shot one that was low by about 30FPS, and that was how it went after that. It was a spread of over 40FPS and this gun is always consistent. I shot 75 or so shots total, and nothing really remarkable happened except the increased spread in velocity.

I am not using dry lube in the gun, so I am sure that this is contributing to the wide spread. This said, the gun was still really accurate even though my spread was wider than normal.

I went out yesterday to shoot some pest birds with my FX Crown at -5 C for the first time. I was expecting the POI to be effected by the cold but my three zero test shots proved otherwise. The first shot was slightly low then shot 2 & 3 hit the bullseye at 35 yards zero. I was able to connect and drop a few birds ranging from 25-65 yards. The only negative, well two, is the potential moisture being transferred into the gun while doing a fill with my tank as it didn't sound right with the hissing sound of air. And I was uncomfortable after an hour plus of shooting even in the sunny condition. But I was fun nevertheless to drop a few pests and to get some trigger time.

I had my .45 AEA Challenger tethered the other day. It was 22* and I was shooting 30 or 40 shots one after another. When I pulled the fill probe out. The one way valve leaked till it warmed up. When I brought the rifle in, the tube frosted up white as snow. 

Have hunted in some quite cold temps, well below 0. Just watch when you put air into the rifle.

Have to ask Paw.... where you from? Those temps sound quite similar to what I am going to be seeing for the next few days. Up here in the upper midwest things get quite cold this time of year.

I use what Tim Hill puts in his Marauder kits for a dry lube on the hammer. It looks like regular powdered graphite. I actually use it on all my hammers year round now, works great.

last season i filled my texan up to 3600psi indoors, put it in my truck

next morning and when i got to my property to deer hunt, it showed only 3200psi in the tank.

no leaks ever, and still none........i questioned the guy that tuned and performance built my texan and he said its the change in the temps from filling in and hunting in.

no problems just hold a bit over than zero @ 3600psi....

so now on fill gun at outside temps to remedy this problem.

Used my rti prophet in -3 this morning to take some starlings, this afternoon it reached a high of 5 and was still shooting great what a gun...

I was out with my Cayden today (it was 12F) doing a little squirrel hunting. I didn't see any squirrels, but I made a killer 20yd shot at a cattail as I was nearing the car to empty the rifle.

The best way to remedy the pressure drop is to use dry nitrogen and a buster pump there is all most no pressure drop.
