The largest benefit of a longer barrel is increasing the distance between the front and rear sights. This gives the shooter a smaller angle of deviance when shooting.
Some might argue that longer barrels, with longer rifling (lands and grooves) inside the barrel, produce more accurate shots by reducing yaw and precession, but that's probably taking it a little too far.
I tried an experiment when I was first told this a long time ago at an NRA certified training program. I put the same scope on a pistol as a long rifle and my pattern at 150 yards was basically the same.
Additionally, I don't see any significant benefits (in accuracy anyways) between some of the longer guns I shoot and my carbine...
Not necessarily. A barrel shorter then 8 inches will have a hard time getting up to 300 fps, and anything over 16 will take up more air. If the barrel is stationary, a longer barrel will lead to greater accuracy, but if you are moving with a long barrel your shots will be less accurate then a regular one.
wrist
No.
It makes the shot more accurate so youll have a more polished shot, and when it is a little of-target it might roll back in cus of the spin.
a wrist shot, its more accurate than a slap shot EDIT: It depends on the situation. Slap shots are more fun to take and more powerful, but take time and are less accurate. Wrist shots are less powerful but more accurate, but still take a bit of time. Snap shots are quick and accurate, but not quite as powerful. Backhands have almost no advantage and are used out of necessity. I would say the snap shot is the "best shot" because it will allow you to catch the goalie off guard, shoot when being covered, and shoot the puck where you want it to go.
No. It just makes your shot more accurate. Or it also helps if you want some whip on your stick.
layup
Well the most accurate spot for people can be everywhere its just depending on what their playing style is. But usually the closer you are to the basket the more accurate you are going to be. Take the layup as an example,that is usually the most highest percentage shot in the game,meaning most people that take a layup usually make it.
Accurate enough to get the job done.
Yes. Slug barrels have a different "Choke" then shot barrels that make them more accurate when firing slugs, but you can fire slugs with a stock 1200 barrel.
It depends on what type of steel is used to make the shot and what the size of the shot is. The smaller the size, the more it will weight.
No the maximum points you can get in one shot is 3.
it will not be any more accurate, a paintball marker is not a firearm the physics are different. in all reality the first 8" of a barrel are for accuracy, anything after that is to quiet the shot down and give the ball a little more room to accelerate
