You may experience a drop in air pressure. Today, before heading to my shooting range, I filled my 45-minute tank to 4500 psi, but by the time I arrived, it had decreased to 4000 psi. the temp was 25 degrees and there were gusty winds.
You will have to figure out how much extra pressure to fill the tank to, based on how much the pressure drops in the cold. For example, if you normally start your shot cycle at 3200 psi, but the cylinder drops down to 3,000 in the cold, then you'll need to fill it to around the 3,400 so it will drop to the 3200 while hunting.
That makes complete sense but I'm shooting this gun at max pressure and it drops down to 3300
Yes, they do raise up in pressure as they warm back up. In my original post I should have added that I don't leave my tanks that full when bringing them inside after being in the cold weather. One or two shots brings the pressure off enough to allow expansion enough to bring it back up to the warm filll topped off pressure.
Should I give up my Texan or my big 9? For what? Perhaps an FX or a Rattler
. It depends on the situation; sometimes I hunt while tethered.Not trying to be a fan boy, but what's with the new 357 & 45 Rattler's that you would disparage them? They are a decent semi-auto and make good power. Plus made in the USA.Should I give up my Texan or my big 9? For what? Perhaps an FX or a Rattler
No I would not buy any fx airgun for deer hunting. I bought a .25 for critters but it puts out almost 80 fpe which is a dead deer when shot in the head. I like the Texan, but it isn’t regulated. You air up when it happens to be warm and it cools off and your power/accuracy suffers. The accuracy of unregulated guns relies on an accurate fill pressure. I like the Zeus but idk if it is regulated. Whats up with the laugh? I killed a nice doe with my .25…fx….Can you do that?Should I give up my Texan or my big 9? For what? Perhaps an FX or a Rattler
@SLICKNICK This is really strange, especially for person whose profile says that they are in Miami, Florida. I could see if you were living in or planning on hunting in Alaska, Minnesota, or somewhere with crazy cold winters. Why would you place your SCBA tank in a bucket of ice?
I hook my .510 Texan up to my external regulator and scba tank usually..leaving tanks outside in cold then filling .. I hate the cold warm air pressure thing..I perfer a 70 degree heated shooting trailer..Than all is well.. My old boring 22 condor .222 diameter 12 twist will sling 55 grain Cast slugs at 1050 fps..Im sure it can do it kill big game head shots too..Airforce have there place for power in the hunting community...No I would not buy any fx airgun for deer hunting.

Where I use to fill my dive tanks, then would fill tanks in a large cold water container. They told me it stresses the tank less. So that’s the method I used for my PCP tanks as well. But if your tank is close to freezing when it fills, it will stay full if the tank is in freezing weather
@SLICKNICK For SCUBA tanks that makes more sense. Thanks for the clarification.Where I use to fill my dive tanks, then would fill tanks in a large cold water container.
