Moisture, range, no rifling.
All types of guns do not contain rifling but they do shoot little mini david's at high speed velocity....... unfortunately they are deadly weapons to the brain and can dig their way into the stomach and eat you from the inside out.
Among others. Smith & Wesson uses 6/6 in many of their guns.
Some fire shot- a number of lead pellets. Rifling causes the pattern of shot to open, leaving a hole in the middle of the pattern.
So close to zero as being unmeasurable. The variations in markings come from random variations in wear of the rifling cutter, odd chips of steel produced by the rifling process, etc. Even two guns made in succession on the same production line will show differences in produced striations.
A good start would be a gun shop- most sell used and new guns. See the Yellow Pages phone book under Guns.
no, a rife shoots 1 projectile and the barrel has spiral grooves in it which are known as rifling. A shotgun shoots multiple projectiles at a time, and the barrel is smooth.
the micro groove is button cut and ballard is the lands and grooves are not equally spaced
hand guns , long guns, Air guns , Rifle these are used as a firearms .
broach is the tool to cut rifling.
Smooth bores are bores or barrels in guns that do not contain rifling. Rifling is made up of lands and grooves that cause the bullet to turn within the barrel of the gun. This turning gives the bullet and gun its accuracy. A smooth bore gun is much less accurate than a rifled bore gun.
The were used from the very beginning. The tanks overran Poland in days.
