http://www.pilkguns.com/aphp/aphphome.htm As far as buying one Search "BEEMAN Air guns " he has a good selection. Feinwerkbau air pistols are probably the best . If your looking into rifles the same info applies. http://www.beeman.com/product.htm Quote :"One of the most challenging sports in the Olympic Games is the 10 meter running target. Shot with airguns, this sport demands shooting a bull's eye that is moving across a 6-1/2 foot opening in only 2.5 seconds! And to top it off, the bull's eye is only 0.2 inches in diameter! Oh, by the way, all shooting is done from the offhand position and the rifle must remain off the shoulder until you see the target."
