Handloading ammunition avoids the labor costs of commercial production lines, reducing the expenditure to only the cost of purchasing components and equipment.Reloading may not be cost effective for occasional shooters, as it takes time to recoup the cost of needed equipment, but those who shoot more frequently will see cost-savings over time, as the brass cartridge cases and shotgun shell ...
For shotshell ammunition, the technical variations are easier to solve since only one type of piezoelectric sensor (called "tangential sensor") is available from the PCB Piezotronics and Kistler International companies to be used without drilling without variations amongst SAAMI guidelines and C.I.P. rulings.

For American shot, a useful method for remembering the diameter of numbered shot in inches is simply to subtract the shot size from 17. The resulting answer is the diameter of the shot in hundredths of an inch. For example, #2 shot gives 17−2 = 15, meaning that the diameter of #2 shot is 15 ⁄ 100 or 0.15 in (3.8 mm). B shot is 0.170 in (4.3 ...
For example, the SAAMI maximum pressure for the 7.62×51mm is given as 52,000 psi (CUP), or 62,000 psi (430 MPa); the .45-70, on the other extreme, is listed as 28,000 in both CUP and psi (190 MPa). SAAMI standards for a given cartridge may be expressed in CUP units, LUP units, or in standard units of pressure (psi or MPa).
The Marshall-Edgeworth index, credited to Marshall (1887) and Edgeworth (1925), [11] is a weighted relative of current period to base period sets of prices. This index uses the arithmetic average of the current and based period quantities for weighting. It is considered a pseudo-superlative formula and is symmetric. [12]
Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
Gauge of a Shotgun is defined as a list include all necessary data to define a functional Barrel. For example the Dimension of the Chamber, the Shotgun bore Dimension and also the valid Proof Load and Commercial Ammunition as defined in by the C.I.P. for Greater Britain in the APPENDIX I of the: RULES, REGULATIONS AND SCALES APPLICABLE TO THE
A US Marine practices shotgun door-breaching techniques. A breaching round or slug-shot is a shotgun shell specially made for door breaching.It is typically fired at a range of 6 inches (15 cm) or less, aimed at the hinges or the area between the doorknob and lock and doorjamb, and is designed to destroy the object it hits and then disperse into a relatively harmless powder.
