Both a pellet gun and a BB gun are similar in appearance But here is the main difference. Most BB guns have a smooth bore barrel. The BB just tumbles as it flies through the air. BB guns are not very accurate. The BB also doesn't deform when it hit the target. It's a very poor choice for hunting small game. However they are fun and inexpensive to shoot. Most will not attain a speed of much more than 400 feet per second (FPS.) Pellet guns use several different shape pellets. Some are for target shooting some are for hunting and other uses. Pellet guns usually have a rifled barrel (One with grooves in it.) This causes the pellet to spin as it travels to the target. This spinning make it more accurate just like a real bullet. The pellet is made of a softer material than BB's and when they strike the target they deform causing more damage to the target. They are ideal for hunting small game like rodents and birds. Pellet guns can attain a speed of over 600 FPS and pellet rifles can reach speeds of over 1,200 FPS. BB are .175 or .177 Caliber. Pellets come in .177, .20, .22, .25, 9mm, 45 Cal and 50 Cal. The last 3 LARGE calibers are used the PCP guns and Rifles (PreCharged Pneumatic air guns) They are capable of bringing down a moose. However PCP guns and rifles are very expensive. Pellet guns are less expensive and BB guns are the least expensive. Now don't confuse BB Air guns with Air Soft guns. They both shoot BB's but air guns shoot steel BB that are small and Air soft guns shoot plastic 6mm BB's. Air soft guns are considered toys while air guns are not. An Air gun is a gun so handle it with safety in mind. == ==
