The Definition of Controlled Pair
Two shots fired in rapid succession. It is different from a double tap because in a controlled pair,
the second shot will be fired after the shooter has obtained a second sight picture,
whereas in a double tap both shots are fired based upon the initial sight picture alone.

The front sight is placed at the muzzle end of the barrel. It is often (but not always) in the form of a dot or a blade.
To attain a proper sight picture and shoot with the greatest degree of accuracy, the shooter's eye
should be focused sharply upon the front sight while shooting, allowing both the rear sight and the target to blur somewhat.
A shotgun barrel that has a bore diameter increased beyond standard specifications, but less than the SAAMI maximum.
Done in an attempt to reduce felt recoil, improve patterning, or change the balance of the shotgun.
The bevelled portion of the rifling at the rear end of the barrel (and the forward portion of the chamber) where the bullet first engages the lands.

It was invented by Captain John Norton of the British 34th Regiment in 1832, after he examined the blow pipe arrows used
by the natives in India and found that their base was formed of elastic locus pith, which by its expansion against the
inner surface of the blow pipe prevented the escape of air past it.
A semi-automatic pistol in which the barrel and breechblock are locked together for the full distance of rearward recoil travel,
