Winter 12g Cartridges?

[bettega]

Hello;

I am aware that there are bulk compressed air tanks available to screw into CO2 guns like the Hammerli 850 or Archer QB's that downregulate 3000+psi of compressed air to the ~1100psi required for safe use of the CO2. Fair enough, but I have a few guns that are unable to accept these larger tanks and some search revealed the possibility of compressed air or nitrogen tanks in the ~12g size. Unfortunately a search to purchase these shows they are very expensive. Anyone know or try using or know where to buy compressed air or nitrogen like tanks that are not subject to cold effects like CO2 so that I can shoot air pistols and the like outdoors in the winter?

Many thanks

What type pistol are you shooting.

I was thinking of a heating system to RAISE the pressure in Co2 rifles just enough to send .22 caliber pellets downrange at 1000 fps or so ....I'm probably wrong about heat creating more power BUT a battery powered sleeve heater (winter sock temperature) would allow Co2 shooting at any elevation ... just a thought....one way to test... put a winter sock around a pistol handle....

Could try these

Brilliant ... a ten pack even....

I modified my QB78 top pcp co2 problem solved

 buying heat packs would be easier AND work for the OP ... in the video below this guy coverts a QB78 and gets 10 shots per fill ... the video link is...

Did mine just a little different about half the weight but only get 4 shots lol

Beautiful rifle

4 shots is real with that set up.
10 shots may well clear the barrel but you would NOT be shooting 40 yards on the 10th!
Thinking QB, bulk fill end cap.
Rigs that seal on the cartridge ( not with a sealed tube) you can tap a hole in the side and run a line there, aka " dummy cartridge".

Hand warners can easily go over 100degrees , valve lock and ?????? Also they are made from Rust ( Iron Oxide) and Salt Water +++ dont rupture one near your rig.

Raining on our parade? arrrrgghh..... Ok ditch the warmers ... I do believe a small battery operated sleeve would work AND sell... at HacksDay they're running a button battery contest... a Co2 sleeve challenge would be right up their alley ..Or a pistol grip sleeve...

If you have a co2 airgun in a car during the summer will easily get over 100 degrees and I safely pump this to 2000 pounds during the summer but in winter it will lock up above 1800
and if you wanted to do bulk fill just use a bottle with hose.lol

I was thinking along the car heat lines as well... goes to 150 here... now we have a max psi to stay below 1800 I'd say keep it below 1500 and good to go... thnx

Man they're not kidding. Got an Umarex Colt Commander for Christmas. I heard 60-70 shots and I was cool with that - it's still loads cheaper than 45ACP. But yesterday/today it was down in the 30's. I got about 30 - 40 shots on my first 12g tank.

But you got those 30 to 40 shots for the price of a single 45 round. Lol

Pretty much. It's why I got it. 

Plus it was so freaking cold that it just wasn't fun.
