yes 50 metres is pretty good if ur using a spring or electric bb gun. it is average for a gas bb gun. the average for an electric/spring bb gun is 30m
In a BB gun (Not airsoft) this is considered very slow.
it all depends on the make and model. You did not say what kind of BB gun.
Yes I can
Pretty much outside the scope of a hobbyist
Most good sporting good stores carry them. You can also find them on the web, just search for "BB GUN "
In the truest sense of the definition of "automatic", no a bb gun cannot be automatic. In function, however, a BB gun can be automatic. A good example would be the Drozd BB gun which fires full automatic, but used CO2 as the power source.
They would be better than 14 BB gun.
You need to Identify the make and model of the BB gun in order to get an answer not the serial number
Colt makes a 1911-A1 Pellet gun made by Umarex. I know of no BB gun unless you are asking about an Air Soft gun. The Pellet gun is very good. I can not answer about an Air soft gun.
Any gun can just as easily hurt its owner as anyone else. There are many companies who make BB guns that will last for years
If its a BB Gun, Then Yes.
