Neither. Both perform as intended.
Pellet is more accurate and more expensive.
ADDING: If you like to shoot rapid-fire, there are more options for semi-automatic guns among BB guns. A round steel BB is easy to load and to make a gun self-loading (loads into the chamber). Most pellet guns have to be loaded by hand, one shot at a time, although there are a few models that use 5 shot clips that look clumsy to use.
A metal BB is a hard ball, usually .177 in size. It's fired through a smooth bore barrel. BB"s are not very accurate beyond 30 feet because they tumble as they fly through the air.
Pellets are usually made from a softer material like lead. They have a skirt on the rear of the pellet to catch the air from the rifle. They also can be fired through a rifled bore barrel (one hat has grooves in the barrel) the skirt on the pellet catches the grooves in the barrel and the grooves make the pellet spin. This spinning is just like a real bullet and this also makes them very accurate over a long distance. Pellets come in different shapes and weights. They also are made for different size pellet rifles. And can become very large for big bore air rifles used for hunting. However most pellet rifles usually come in the smaller .177 and .22 calibers. Think of it this way. Pellets are the big brother to BB's
It all depends on what you want to hunt with. I suggest a .22 cal pellet rifle as a good choice. The pellet is larger and has more knock down power. Use a heaver weighted pellet. Stay away from light weight pellets, they do not fly as straight as heavy pellets (use something around 14 grains in weight) If you want to just plink at targets then purchase a .177 caliber pistol or rifle and use "Match Pellets" for good results. Always look for pistols or rifles that have a "rifled" barrel not a smooth bore barrel. Smooth bore barrels are not as accurate as rifles bore barrels. (Grooves in the barrel make the pellet fly straight.)
The compressed air gun, which shot metal bb's was invented before the paint marking gun.
A paintball gun is several magnitudes stronger then a Nerf gun. A paintball travels at around 200 mph, where a Nerf gun is around 10.
They run on the same concepts, having a compressed gas propel them. But bb guns are generally more powerfull, slower shooting, "classic" looking rifles and pistols. Paintball guns are either military simulation or built specifically for the needs of paintball players, that look nothing like real guns or bb guns.
Not easily. The modification would cost more that it is worth.
In general scopes are not very useful in Paintball due to the relative inaccuracy of the Paintball itself and the tunnel vision effect of the scope. but if your Paintball gun had weaver or 3/8 rails, you can mount whatever scope (or sight, a better option) you wanted on it
No because in Philadelphia it illegal to have type of air soft for example pellet paintball and bb
I would suggest an AirSoft BB gun. Not a Paintball or steel BB gun. Unless you have someone who is familiar with firearms then I would get him a Daisy Buck BB rifle and an adult to teach him the respect and rules of handling the rifle. The "Daisy Buck" is designed as a starter BB rifle for youngsters.
Paint balls. the hurt way more, and the paint its self can do some damage too
No. Firstly you should not be shooting bb guns at each other. Second, you can not play any sort of wargames (paintball, airsoft) in public areas.
You must be 18 to buy bb and paintball gun accessories.
The purpose of a paintball gun is to fire paintball pellets, to mark opponents in the game of paintball.
Pellet guns are more powerful. They are stronger because they use a CO2 Gas, whil BB guns are spring-powered.
