For the.300 Weatherby, Roy Weatherby drew on his prior experience with bespoke cartridges like the.270 Weatherby Magnum. This cartridge, like most of his others, is based on a.300 H&H Magnum case that has been blown out and features the distinctive Weatherby double-radius shoulder. Both the Weatherby and the.300 Winchester Magnum were initially offered to the public in 1944 and 1963, respectively.
Rifles in this caliber have been made by Remington, Winchester, and Ruger in recent years, and factory loads are available from most major ammunition producers.
Although Weatherby formerly said that their.30-378 Weatherby Magnum was the most powerful.30 caliber magnum rifle on the market, the introduction of the.300 Remington Ultra Magnum and the.300 Norma Magnum have both proven them wrong. There are, of course, several very huge wildcat.300 rum ammo.
However, there is a distinction in factory loadings for the.300 RUM and the ultra mag ammo 300 rum. In order to facilitate in-store comparisons, performance information is typically published on the side of the ammo box. Typically, Weatherby factory ammunition has higher chamber pressures than Remington or Winchester magnum cartridges. Because of its superior potential when handloaded to comparable pressures, the Remington round easily outguns the.300 Weatherby.
The300 rum ammo in stock is a popular choice among big-game hunters around the world.
