9mm Major is a wildcat cartridge of the 9mm Luger specifically for competition pistols designed to handle very high pressure. It is used in practical shooting competitions like International Practical Shooting Confederation (IPSC) and United States Practical Shooting Association (USPSA) to achieve a "Major" power factor, which earns more points for hits in specific zones on paper targets ...
However, QuickLOAD has limitations, as it is merely a computer simulation. It does not account for different brands of primers for example, and its ability to predict the effect of seating bullets into the rifling is crude. A QuickLOAD user most certainly should not just "plug in" a cartridge, bullet and powder and use that load, assuming it is ...
In the classic division a choice can be made between up to a 10-shot capacity 1911 with minor scoring (e.g. 9×19mm) or up to an eight-shot capacity 1911 with major scoring (e.g. .40 S&W or .45 ACP). In the revolver division major scoring can be achieved with a 9 mm bullet diameter, but with a power factor of 170.
Since the rifle was designed for use on Alaska's great bears, Johnson cut 720-grain (47 g) boat-tail .50 BMG bullets in half, seating the 450-grain (29 g) rear half upside down in the fireformed .50-caliber case. It didn't take Johnson long to find out that the truncated-shaped "solid" would shoot through a big brown bear from any direction ...
(or 6.5mm/06) - necked down to accept a 6.5 mm bullet - The 6.5-06 offers ballistic performance between the commercialized 25-06 Remington and 270 Winchester with distinct advantages over both in particular long-range applications through a wide selection of bullets with high ballistic coefficients producing better extended range performance.
Shoppers at select grocery stores around the South can pick up something new: ammunition dispensed from a high-tech vending machine that contains a plentiful assortment of 12-gauge shotgun shells ...
The M855A1 bullet has a 1 ⁄ 8 in (3.2 mm) greater length than the SS109/M855. [141] Because steel and copper are less dense than lead, the bullet is lengthened inside the case to achieve the same weight as its predecessor. [10] The longer bullet and reverse-drawn jacket make it more stable and accurate in-flight.
Increasing the case length. This process (which allows the cartridge to contain more propellant and thus increases the potential energy of the bullet) was used to make the powerful .357 Magnum cartridge from the much weaker .38 Special: A .357 magnum bullet has more than 3 times more energy than a .38 special bullet of the same weight ...
