Swiss Arms 12-gram CO2 Cartridges, 100ct

Things I liked: I've used these before, and when I saw PA had them in quantity at a good price, I bought 200 of them. I really cant tell the difference between brands of CO2. I only know all of them seem to work in my 26 CO2 pistols and 16 rifles. I was using Crosman only, but read an article that purported Crosmans had some residue in them where as Umarex, Swiss Arms, Gamo, and others were much cleaner inside. I never sawed any cartridges in half to verify it. Crosmans seem to work fine, and a drop of oil on every brand seems to keep my guns working flawlessly. Bottom line, price determines which cartridges I buy. At 46 cents each, these are good value, less with the discount and free shipping. I can buy Crosmans for about the same price, 40 at a time, at the MegaloMart but rather support PA, and get a discount and free shipping most of the time. And if these other brands are really cleaner inside, it's not just a good deal, it's a great deal.

Things I would have changed: Nothing

What others should know: I'd really like to see PA do a scientific evaluation of CO2 brands to rank them in terms of cleanliness, volume, price, etc., the way many companies and publications rank other products. We need a "consumer reports" for the air gun industry. By the way, I think it would help sales, not discourage them, and it would motivate manufacturers to do the best they can with what they produce. Over the past year I've become very active in the hobby/sport, and almost every single thing I've purchased has been top quality. Like they say, even a bad day airgunning is a good day.
