Re: throw 'em in prison and throw away the key
Hopefully I'm not coming off as a gun nut. Its just a hobby to me much like golf for others. Honest, I don't even own any camo clothing!
But anyhow, there are several different .22 cartridges:
.22 BB, .22 CB, .22 Short, .22 Long, and .22 Long Rifle.
The .22 Long has a 29 grain bullet and is less accurate than either the Short or Long Rifle due to its ratio of grain weight to propellant. It has a projectile velocity of about 1,240 fps.
.22 Long Rifle has a standard size bullet of 40 grain with a velocity of about 1,130 fps to 1260fps with hunting of game up to about 7 pounds.
.22 short usually has a 29 grain bullet and is mostly used for practice by the recreational shooter. For hunting it is best for only for tiny pests like rodents, and small birds.
Hope this answers your question.
