Case of 450 12 Gram Unthreaded CO2 Cartridges Airgun

Not that many shots from this CO2 cartridge. I would say 20-25% less then Crosman CO2s ones. Still good buy price wise.

Reasonable usage from each unit. This was a large quantity of cartridges. Quite a bit of weight for all of them.

I was sent a large case of Swiss arms 12g cylinders, not Lelands. They seem to work fine by the few that I have used, but I have years of great experience with Lelands which led me to buy these.

Not really much to say about it. It was a box with 450 co2 cartridges in it. Shipping weight is listed incorrectly for the picture. If you order it, you can't be a wimpy little nerd who can only lift 30 pounds on your best day. The box with all the cartridges weighs 45 pounds. Not enough to even phase Chuck Norris(he lifts that with his beard all day long without flinching), but we all know that none of us are a regular Chuck Norris. Do they work? That's kind of like asking if a Ferrari is fast.If you want a lot of co2 cartridges, here is a good option. I notice they shoot A LOT more shots than Crosman cartridges. Only thing is they dont have oil in them, so if you have a gun that you want to keep oiled and maintained, I suggest you pick up a little gun oil for it too. I would love to write more of a review, but I have to go back to shooting zombies. Take it easy!

If you play paintball and use 12 grams then this is your best option. I have asked around and the general consensus is that for paintball use Lelands are the best. I can't claim to have tested all of these but according to my research leland 12 gram co2 cartridges are filled more consistently which means that you can expect to get the same number of shots out of each cartridge, the cartridge itself is also consistently the same size and shape. I use these in my Tippmann Tipx and love them. I split the order with 2 other friends but I think next time I order I will split with only one other or maybe keep them all for my self. all depends on how long the ones I have last me.
