The Definition of Frangible
A bullet that is designed to disintegrate into tiny particles upon impact to minimize their penetration for reasons of range safety,
to limit environmental impact, or to limit the danger behind the intended target. Examples are the Glaser Safety Slug and the breaching round.

Abbreviation for Caliber.

An imaginary line which runs right down the center of the handgun's barrel and out though the back end of the gun.
A handgun may have a high bore axis, with the imaginary line running out into space well above the shooter's hand.
Or it may have a low bore axis, with the imaginary line running either straight through the shooter's hand or
just skimming the surface slightly above her hand. A high bore axis tends to create greater perceived recoil
and more muzzle flip when firing the gun than does a low bore axis.
Small caliber bullets being used in large cases. E.g. .22 bullet in a .45 acp case.

Helical grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis.
This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy.
Plugs of hardened steel, precisely machined in relation to the standard dimensional specifications of a given cartridge,
normally in sets of three: "GO", "No-Go" and "Field". By loading these plug-gauges into the chamber in succession,
one can check that the action should close on the "Go" gauge. It should not close on the "No-Go" gauge,
but might were enough force to be used. And, it absolutely should not close on the "Field" gauge.
The point at which the trigger allows the hammer to fall, or releases the striker, so that the shot fires. The ideal trigger break is sudden and definite.
"Like a glass rod" is the cliche term shooters use to describe the ideal crisp, clean break.
