A rifle projectile made with the tip of the bullet open as a means of increasing accuracy as compared to standard military bullets that are made with a closed tip and an open base. The are not designed to expand like a hollow point bullet but may fragment.

Cast On

An offset of a gun stock to the left, so that the line of sight aligns comfortably with the left eye while the butt of the stock rests comfortably on the left shoulder. Almost all left-handed shooters benefit from a little caston and most custom built guns are made this way. The only question is how much. The caston of a gun is about right when, with the gun comfortably mounted, the front bead lines up with the center of the standing breech.
A stock offset to the right, for shooting from the right shoulder is said to be

Crosshairs

The cross-shaped object seen in the center of a firearm scope. Its more-proper name is reticle.

Knuckle

The curved, forward end of the bar of a break-open firearm's action, about which the mounted forend iron revolves downward. This area should be kept lightly greased to avoid galling the bearing surfaces.

Side-By-Side

A shotgun with two barrels which are situated next to each other. Somtimes also abreviated as SxS.

Benchrest

A device used (usually set on a counter) to support a shooters arms and/or hands to help make steadier shots.

Field Gun

A shotgun, generally stocked to shoot where it is pointed and of relatively light weight because one often carries it a great distance for upland birds, the consequent recoil not being an important factor because one actually shoots it very little.

Extractors

A part in a firearm that serves to remove brass cases of fired ammunition after the ammunition has been fired. When the gun's action cycles, the extractor lifts or removes the spent brass casing from the firing chamber.

X-Mark Pro

A trigger system designed by Remington Arms Company.

The mechanical sighting system which usually comes with the firearm made of metal with no optics.

Fouling Shot

A fouling shot is a shot fired through a clean bore, intended to leave some residue of firing and prepare the bore for more consistent performance in subsequent shots. The first shot through a clean bore will behave differently from subsequent shots through a bore with traces of powder residue, resulting in a different point of impact.

A short stock, often ideally sized for teenagers, average-sized adult women, and small-statured adult males.

Breechloader

A firearm loaded through the breech.

Self-Opening

Attribute of a break-open gun whereby the barrels drop down simply by pressing the toplever without muscling them open manually. The Holland & Holland system utilizes a coil spring within a cylindrical housing mounted just ahead of the forward lump to urge the barrels open. The Purdey system utilizes residual energy remaining in the mainspring after the gun has been fired. Both systems enable a shooter to load more quickly when birds are coming fast.
