hot hands to keep Co2 warm in winter ???

[DBOdude]

i don't have a Co2 gun , but i was wondering if anyone had tried using a hot hands heating pack to keep the tube warm ....



or will it get too hot for the Co2 or even possibly hurt the gun or shooter ?

That looks like an accident waiting to happen. Besides, it won't do any good to heat up the cart if the gun is cold. And the first 5 shots, the cart will be cold again. Wait for a nice warm day or be inside where it is nice and warm.

i was thinking of using a rubber band to hold it under the Co2 tube in front of the trigger grip . but if if it's a accident waiting to happen ...... it is what it is .

how would it be an accident waiting to happen? those things don't get hot enough to burst a CO2 cart, I have a 2240 and a bunch of those, if it's still cold this weekend I might have to give it a shot

[DBOdude]

please get more input before trying it . i'd hate for someone to possibly get hurt because i had a bad idea .

If you had the leland carts from Red rock you would be safe. Crosman carts say not to heat over 120. Why don't you try it and see what happens, then you could tell us if it works or not.

Those things are so weak you'd be lucky to hit 50 degrees on a freezing day.
Personally I would try this type of sodium acetate based reusable heat pack: http://hotsnapz.com/
They don't use oxygen and heat up reliably. Hotter but for a shorter period of time (better for a couple rounds of shooting) and they are a liquid gel product, so they reach a max temp of ~100F

Best of all they are reusable! If you have a few you can use them up and then boil them all for the next round.

None of these will do us any good here - it is 20 below today so the pellets just flop out of the CO2 gun.

From the ANSI & DOT websites, and this relates to cylinders with rupture-discs so... for 12gr "crimp-top" cylinders, Crosman states 120 F Max and that is indirect heat, not contact or otherwise, but you can "make-up" your own temp limit  depending on how lucky you feel  

"Each cylinder is provided with a safety relief disc which will release the gas before the pressure exceeds the cylinder test pressure. Cylinders should be stored in a cool place whenever possible. The maximum safe storage temperature for all cylinders up to and including 35 lb. capacity is 140 degrees F (6O degrees C), and for cylinders of 50 lb. capacity or over is 150 degrees F (65 degrees C). Special cylinders can be supplied for higher storage temperatures."

Or as they say in the ANSI engineering dept.  "do you what you want but you are now a test-pilot, call us from the scene of the crash if you survive"

If you are paying attention it will give a boost to pumpers but you need to pay attention...

so basically you use Ideal gas law( PV=nRT) and you will see a 50* f rise in the temp of the air will give about a 10% boost in psi...

that is why my MK 177 hit 1024 fps instead of bout 920-930 fps with a .242ci valve... instead of 1600-1700 psi I got 1760-1870 psi

so if it is 20-30* f out and you can keep your valve at 70-80* f...

Are you using CO2 cartridges in your pumpers 

[K.O.]

I should have been more clear

no I would not with co² but with pumper it is a bit different...

I was just joking.  Your comments are very clear and all your posts are precise and informative.

I have used the Hot hands in insulated mittens and ordinary shoes or boots.
They do not get hot enough to burn skin, normally.
I seriously doubt they will raise the temp of a CO2 cylinder to dangerous levels.
If you apply it to an air tube, first it has to heat the air tube, then the heat will transfer to the CO2 cylinder.
Insulate the area around the CO2 bulb,Over the Hot Hand, because the packet doesnt give off much heat.  If you don't insulate it with something, the heat will just be given off to the surrounding air
Touch the area frequently to see if it is getting noticeably warm. 
If you hold one of these in your hand, they dont feel really hot, even inside your mittens.
120 feels Really Hot!.
Look at the pic on the package, a hand holding the thing.

I have been also thinking of  keeping things from cooling with hand warmers.  Last winter, experimented some with warming the 2400KT by the heater before going outside.  I put the gun under my jacket, and went out and shot some.  This was a cold, clear day and between shots, I placed the gun in the direct sunlight with a reflective backdrop.  When the gun got cold after a few shots, I put it in the house to warm up and took my 1377 out to play while the 2400 warmed up.

This year, I plan to be sure the gun is warm before going out.... using a work light which generates a lot of heat under the car port to re-warm as necessary.  I think the hand warmers may increase the number of shots before re-warming is required.  I will be shooting from the car port this year.

My heating pad might be useful to warm the gun and cartridges some.

I hope to keep the gun warm until I get cold and need to go warm up.

I think I have the proper way to keep a co2 gun happy in the winter.
We are going to LA (thats lower Alabama, not California) for Thanksgiving Dinner.
We'll have at least some time to do a little shooting, in between eating, visiting, and eating.
I somehow ended up with two 2300s, and Darlene likes to shoot at Zombie Targets.
Should be about 60 degrees, just right.
