THANKS FOR ALL THE HELP
This is to thank everybody who satiated my curiousity. Though there are still more questions that need to be answer as they pop up in my mine. The only book I read about gun's was called "The ABC's Of Guns". It was from, like dude, the 1960's. Yike! Just trying to get current info that all. Got 2 more questions: (1) Does the length of the barrel affect the accuracy of the shot out to long distances? (2) What is this rifling thing. I know it helps to keep the bullet from going off course but does rifling the barrel left-handed or right-handed affect anything. Also, what about the length of the rifling? I saw on my fav gun the Bushmaster M4 type was rifled 1 in 7' or something like that. What does that do? Thanks much in advance.
P.S. What's a troll? Not the one that lives under the bridge kind. I know that. The one within the context of here.

Barrel length affects VELOCITY, up to a point. If you cut a barrel back to where all the powder charge isn't being burned, then you will lose some velocity. Once the charge is burned, any more barrel length is superfluous, from a velocity standpoint.
The longer the barrel, the further apart you can hang the sights. The longer the sight radius, the easier to spot sight picture error, so the more accurately you can shoot.
In the .22 LR, for example, the powder charge is burned up in about 14 inches. After that, the extra barrel length is there to satisfy government requirements, sighting, and esthetics.
In the 12 gauge shotgun, with 2 3/4" shells, most of the powder is burned in about 21 inches. Most shotgun barrels are longer so they swing more smoothly.
Rifling is grooves cut into the barrel. The grooves are cut in a spiral, so as to impart spin to the bullet. This helps stabilize the bullet in flight.
1 in 7" means that the bullet turns one revolution for each 7" of barrel it travels. Different rates of twist work better for different bullet weights.
A troll is someone who stirs up trouble on a message board. You may have been initially (and mistakenly) identified as such, since you came on like gangbusters with a whole lot of posts in a short time. I looked at your posts and you seem to me to be a new enthusiast who is asking a lot of questions.
Keep asking.
And welcome.

A quick addition to NUNN's excellent response. Generally speaking, the faster the rifling twist ( 1" in 7" is fast where 1" in 16" is slow ), the better it will stabilize ( spin concentically ) a heavy bullet. You can see the range of available bullet weights in a given caliber/cartidge by picking up a free reloading manual (paperback type
) from your local gun shop ( IMR makes one that is pretty comprehensive for a freebie ). EX. The 22 Hornet and .223 Remington use the same bore diameter. The Hornet will not stabilize anything over about 45 grains in bullet weight because it has a 1" in 16" twist rate (most all manufacturers use this twist rate ) but the .223 Remington ( the M-16 cartridge ) will handle bullets up to around 70 grains because the twist rate is often 1" in 9" ( and even faster sometimes ). Don't let some of the grumps out there get you down! You have come on a little fast and hard with the questions but you have to learn somewhere and I think you will find this a very nice and extreemly knowledgeable group of people as evidenced by NUNN and a lot of the others! Have fun and be safe above all!
