Our take on the Umarex 12-gram Co2 Cartridges, 40ct

Umarex 12-gram CO2 cartridges are the standard power source for most CO2 air pistols, air rifles and pellet guns. Each cartridge holds 12 grams of liquid CO2 and is sealed with a thin neck that the gun's piercing pin punctures on installation. The 40-count pack keeps a full season of shooting on hand and matches the cartridges most makers specify. They suit target shooters, backyard plinkers and anyone running a CO2 pistol who wants a steady supply of the common 12-gram size.

Questions and answers

Will these fit my CO2 air pistol?
They fit any airgun that takes standard 12-gram CO2 cartridges, which covers most CO2 pistols and rifles. Check your gun's manual for the cartridge size it specifies.
How many shots does one cartridge give?
It depends on the gun. A CO2 pistol typically gets several dozen shots per cartridge, while a rifle may get fewer. Velocity and shot count fall off as the cartridge empties.
Do they work in cold weather?
CO2 pressure drops as temperature falls, so shots get weaker and fewer in the cold. Warm the cartridges before use and keep the gun warm for more consistent power.
Are these the same as the cartridges sold with airguns?
Yes. These are standard 12-gram CO2 cartridges of the type most airgun makers supply or recommend.
What is in the box?
40 sealed 12-gram CO2 cartridges. No adapter, oil or case is included.
Where is the Umarex 12-gram Co2 Cartridges, 40ct cheapest?
At Walmart, for $45.00, as of our latest check.
