Hello everyone. recently i was at a Walmart and saw these air rifles made by gamo, they shoot pellets and are powered by air. one is a .177 caliber pellet, and it shoots at about 1,200 feet per second. the other one was a 22 caliber pellet but it fires at 900 fps. im buying one since 22 lr is hard to find in my area. but im not sure which one i should buy Does anyone here know about air rifles? Should i get a .177 caliber or the 22? Wich is best for rabbit hunting at 50 yards or more? The .177 is lighter and faster the .22 is heavier and slower.
