Monolithic bullets have been used for hunting big game in the USA for decades. The first popular all-copper bullet was the Barnes X bullet in 1986. [7] Since then, most bullet companies have a monolithic bullet on the market, including Nosler E-tips, Hornady GMX, Barnes TTSX, LRX, VOR-TX, Federal Trophy Copper, Winchester Powercore 95/5, Hammer bullets, Cutting Edge Bullets, Lehigh Defense, G9 ...
Due to the cartridge's relatively short case and powder column, longer bullets and those with a lower weight to length ratio—such as mono-metal bullets like the A-Square Monolithic Solid and the Barnes Banded Solids—may take up valuable powder space and lead to lower velocities and reduced performance. [6]
Spitzer bullets with better ballistics such as the Barnes X or TSX bullet provides better down range performance over the more conventional .45 caliber (11.6 mm) bullets. The .458 Lott does well with hardcast lead bullets.
Hard cast solid bullet (left), with gas check (center) and lubrication (right) A modern centerfire cartridge consisting of the following: 1. bullet, as the projectile; 2. metallic case, which holds all parts together; 3. propellant, for example gunpowder or cordite;4. rim, which provides the extractor on the firearm a place to grip the case to ...
The 300–350 gr (19–23 g) bullets similar to the Swift A-Frame or Barnes TSX bullets are appropriate for heavier non-dangerous game. Lighter dangerous game such as leopard and lion are best served with lighter bullets which open up rapidly or bullets which fragment upon impact such as the A-Square 400 gr (26 g) Lion Load.
The .458×2-inch American was designed as a medium-power big-bore cartridge by Frank Barnes for North American big game. Frank Barnes found that the .458 Winchester Magnum and the .460 Weatherby Magnum too powerful for North American big game and believed that a cartridge of lesser power would be ample for the task.
Furthermore, the Barnes cartridge is capable of launching heavier bullets than the 7.62×39 and has the advantage of using spitzer bullets and is chambered in strong bolt-action rifles, whereas the .30-30 is commonly loaded with round-nose or flat-nose bullets due to the fact that it is chambered in lever-action rifles with tubular magazines.
Monolithic bullets such as the A-Square Monolithic Solid, [23] Barnes Banded Solid, [24] Supreme Nosler Solid [25] and more conventional tougher FMJ bullets such as the Hornady DGS [26] are good choices as they are able to withstand stresses placed on the bullets by the velocity of the .460 Weatherby Magnum. At the 250 yd (230 m) mark, the .460 ...
