just been thinking of it. I also think it would be more of a challenge. getting in close and making a good shot. I know most will not. some take airguning seriously. some good airguns can get expensive and some would like to use them for more then just shooting tin cans in the yard. not to mention ammo is very cheap.
airguns can be regulated just like bows and crossbows. they have minimum draw weights, cutting edge. you don't use 50lb crossbow pistol to hunt deer with do you? I believe airguns can be regulated very easy. minimum fps, minimum ftlb of energy.airguns have come a long way since red ryder bb guns.
