What is apparent from testing is that penetration stops increasing at impact The .458 Lott was designed to be an African dangerous game rifle cartridge particularly for use against heavy, thick-skinned dangerous game such as elephant, Cape buffalo and rhinoceros. According to Arthur Alphin, the cartridge length was standardized at 2.800-inch (71.1 mm) and the chamber length at 2.810-inch (71.4 mm) because there were many converted rifles in the field that were chambered for the original Jack Lott length. There's a pile of people who have written comments and opinions about the 460 Weatherby Magnum, and most of them head off in the direction of whiny complaints. However, the mono-metal bullets fall short of this velocity threshold due to the need to seat the bullets deeper owing to the length of the bullets and the need to stay within the maximum overall length specification of the cartridge. The Lott has no such issues and takes well to lower powder charges. With lesser FMJ bullets only heart, lung or shoulder shots should be considered. If you decide on buying one, just know that it will most likley be sold soon after purchase. speeds above about 1250-1300 fps. understood.

The .458 Lott was soon commercialized by A-Square as a proprietary cartridge. pursuit of the heaviest game. The better ballistic coefficients translate to better longer range performance. Case capacity and performance is slightly greater than that of the .458 Lott resulting in less 50-foot-per-second (15 m/s) in velocity at equal pressures. Distance between lands is .450-inch (11.4 mm) and between grooves is .458-inch (11.6 mm). An advantage that the .458 Lott offers over voluminous cartridge such as the .450 Rigby, .460 Weatherby or the .505 Gibbs is that it can be easily adopted in rifles actions which are regularly manufactured with little or no modification of the bolt face.

This method of fireforming left the newly formed cases slightly shorter than the parent cases. is nothing that can be observed which supports the assertion that the faster The specifications published by SAAMI reflect this fact. about 1600-fps, there is a very definite and measurable decrease in penetration This, together with the ability to load the cartridge to lower power levels, easily adds to the versatility of the .458 Lott. Ovny, if you haven't shot your 458 Lott, I would suggest you do so. assertion that higher speed projectiles are more capable of inflicting the deep This capability easily exceeded the performance that was expected of the .450 Nitro Express and the .458 Winchester Magnum.
