Shorter barrels = less MV
Muzzle to bolt face
No, it must be permanently attached, meaning welded, to count as part of the barrel length.
Foot pounds in muzzle energy refers to the amount of energy expended during the exiting of the projectile from the end of the barrel (muzzle). This foot pounds will vary depending on the grain weight of the round in question, the caliper of the round being fired, the length of the barrel, whether you have a head wind or a tail wind. In other words it is what pushes the projectile from your gun towards your intended or unintended target.
I am fairly certain it is the rifled part of the barrel, not including the chamber, from the headspace ledge to the muzzle, and including any permanant non-rifled attachments to the muzzle. Therefore, a rifle with a fifteen inch barrel can be legal if it has a muzzle brake or compensator which brings its length to over sixteen inches.
A shotgun barrel length or rifle barrel length starts at the point where the rim of the case touches the shoulder of the chamber and extends to the tip of the muzzle. In most cases, if the barrel is threaded on, yes it would include the threads. lcj
The breech is the rear of the barrel, where a cartridge would be loaded. The muzzle is the front end of the barrel. When fired, a bullet is driven up the barrel, and out of the muzzle.
The muzzle is the end of the barrel.
Too broad a question. Muzzle velocity is determined by the specific cartridge, barrel length, barrel tolerances, etc.
Impossible to answer without more info. Must have the bullet weight, barrel length, and muzzle velocity.
Between 830 and 1300 feet per second, depending on the load and the barrel length.
First be certain that the gun is unloaded. Check twice. With the firing mechanism cocked (so that firing pin does not protrude into the chamber) insert a wooden dowel that is close to the diameter of the barrel into the barrel from the muzzle, until it rests against the closed face of the action. Mark the dowel at the muzzle. Withdraw the dowel, and measure the length of the dowel. This technique is also used with all other firearms EXCEPT revolvers. Those are measured from the muzzle to the face of the cylinder.
Depends on bullet weight, muzzle velocity and barrel length.
