You may try cleaning the firing mechanism and every component of the gun very thoroughly. And then if that doesn't work you can try getting a new box of bullets made for that caliber of gun. Make sure it is a good name brand of bullets that you use. My preferences are ''Federal" or "Remington" shells. ''Remington" shells will probably be your best bet for a Stevens/Savage Arms model. I have had this problem before and I cleaned the firing pin and every single compoonent of the firing and loading mechanisms and it worked like a charm. The main problem was that it had too much old gunpowder gummed up on the old leftover oil and it started jamming the gun.
bullet
The barrel guides and accelerates the bullet out of the rifle, and imparts spin to the bullet to stabilize the bullet in flight.
Yes, a bullet must be the same diameter as the barrel (unless it is a shotgun).
Depends on the speed of the bullet, and the length of the barrel. In the case of a .22 rifle, firing a bullet at 1200 feet per second, from a 16 inch barrel, it will take 1/75th of a second for the bullet to leave the barrel.
Time taken by a bullet to leave barrel is 10-3 Seconds.
The rifling in the barrel. These are grooves cut on the interior of the barrel that twist around and cause the bullet to spin as it passes down the barrel. The spin stabilizes the bullet and promotes accuracy.
Barrel contains the force of expanding gasses, as it pushes bullet out of the barrel.
The gun barrel is the metal part that the bullet comes out of.
the bullet rises because of the rifling in the grooves of the barrel

No. Assuming the barrel is level (defined as perpendicular to the pull of gravity) then the bullet will leave the barrel horizontally and immediately begin to fall, like any other object subject to gravity. There are aerodynamic forces from air resistance, but these do not impart lift to the bullet. Often the gun recoils (per Newton's laws) in such a way as to raise the barrel after the bullet has fired.
The barrel of a firearm is the tube through which a bullet travels when a gun is fired.
