The round was designed with a possible military need for a cartridge for anti-personnel, anti-sniper, and anti-materiel roles with a (supersonic) precision range of 2,200 yards (2,000 m). It is offered as a competitor to the most common military NATO long-range service cartridges, such as .338 Lapua Magnum and the .50 BMG .
MV: Muzzle velocity, in feet-per-second; ME: Muzzle energy, in foot-pounds; P: Momentum, in pound (force) (lbf) times seconds. [1] A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters ...
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 ...
The .50-110 WCF / 13x61mmR (also known as the .50-100-450 WCF , with different loadings) in modern 1886 Winchesters with modern steel barrels is the most powerful lever-action cartridge, with up to 6,000 foot-pounds (8,100 J) of energy.
The .458 Winchester Magnum was originally supposed to duplicate the performance of the .450 Nitro Express which could fire a 500 gr (32 g) bullet at 2,150-foot-per-second (660 m/s). On the other hand, the .458 Lott is designed to provide about 200–300-foot-per-second (61–91 m/s) more velocity than the .458 Winchester Magnum.
Conversion from kilo grain feet per second to newton-seconds is trivial, since both the grain and foot is based on SI units. One troy grain is defined as 0.064 798 91 grams exactly [ 1 ] and one international foot is defined as 0.3048 meters , giving the exact conversion factor of 0.019 750 707 768 .

Performance data is often listed on the side of the ammunition box for those who wish to do an in-store comparison. On average, Weatherby factory ammo is loaded to higher chamber pressures than Remington or Winchester magnum rounds. The Remington round can be handloaded to equal pressures, and as a consequence, surpass the .300 Weatherby in power.
