With the advent of chemical primers, it was not long before several systems were invented with many different ways of combining bullet, powder, and primer into a single package which could be loaded quickly from the breech of the firearm. This greatly streamlined the reloading procedure and paved the way for semi- and fully automatic firearms.
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
Large rifle primers are also 0.008" taller than large pistol primers. [14] [15] 0.315" (8.00 mm) diameter .50 BMG primers, used for the .50 Browning Machine Gun cartridge and derivatives; Examples of uses: .38 Special, small pistol standard.357 Magnum, small pistol magnum.45 Colt, large pistol standard.50 Action Express, large pistol magnum
The .303/25, sometimes known as the .25/303 is a wildcat centrefire rifle cartridge, based on the .303 British, necked down to fire a .257 projectile, originating in Australia in the 1940s as a cartridge for sporterised rifles, particularly on the Lee–Enfield action; similar versions also appeared in Canada around the same time.

This primer was created specifically to provide reliable ignition for compressed powder charges in large capacity cases. [52] All reloading manuals provide loading data using only this particular primer to develop reloading data for the .460 Weatherby Magnum. In a pinch the Winchester WLRM primer or primers with similar brisance may be substituted.
Production of Winchester Model 1886 rifles chambered in this cartridge ceased in 1910 due to lack of demand, [3] and most commercial production of the cartridge itself ceased in the 1930s. New production loaded cartridges and unloaded brass cases are rare and are often created using reformed .45-70 brass.
The advantage to this round is the ballistic performance is nearly identical to the .300 Winchester Magnum [2] in a lighter rifle with a shorter action burning 8 - 10% less gunpowder. A disadvantage of cartridge case designs with relatively large case head diameters lies in relatively high bolt thrust levels exerted on the locking mechanism of ...
