An underpowered powder charge, usually caused by a fault in cartridge loading, often insufficient to expel a projectile from the muzzle of a firearm.
If such a blockage is not cleared, the next attempted shot could cause the barrel at least to bulge, and very possibly to burst.
A heat-treating process that incorporates carbon into the surface molecular
structure of the steel, providing a hard-wearing surface without making the entire
receiver brittle. The parts to be casehardened are packed in a crucible with
carbon-rich media such as bone meal and charcoal, heated to bright orange, about
1800°F, then quenched in bubbling oil. Also
A bolt action which is locked by pressing the bolt handle in and down, thereby turning its locking lugs into the receiver.

It is classified as a "Flammable Solid" by the Department of Transportation.
A shotgun pattern with erratic shot distribution, generally caused by gas escaping past the wads and getting into the shot.
An economical method of bringing new life to a damaged pair of barrels, regardless of their original method of jointing.
The ribs are removed. The barrels are cut off 3" - 4" from the breech end and discarded. The bores of the remaining breech-end are reamed out oversize.
New tubes are fitted down into the original breech section and filed down to fit flush. The original ribs are then replaced. Sleeving is considerably less expensive than building a completely new set of barrels. Much of the time required to build a set of barrels is concentrated in the fitting of the breech end to the receiver; this work is salvaged through sleeving. Sleeving can be recognized by a pair of circumferential lines around the barrels a few inches from the breech; the more invisible, the finer the job. A sleeved gun should always be identified as such amongst the proof marks, and if done in England must be properly reproofed. Photo
Sleeving is not the same thing as Monoblocking.
A charge of powder, a projectile or a cartridge. Also, to prepare a gun for firing by inserting ammunition into it.
