“.300 remington ultra magnum”

A beltless non-rebated .30-caliber magnum rifle cartridge designed for extreme performance at long range, the .300 PRC is the product of years of tinkering by Hornady. It will handle almost any game in North America and is fully capable of doing double duty as a long-range target choice.

Both cartridges are based on the H&H belted case, generate impressive velocities and have a wide range of bullet weights. Which is the better choice for the hunter? Contributor Philip Massaro takes a closer look at the pros and cons of each.

The .350 Rigby Magnum is vastly overlooked even among rifle cranks but was at one time as popular as the .375 H&H Magnum. Released in 1908, it is an entirely original design, and was the first to feature the sharp 45-degree shoulder which is the hallmark of the Rigby designs.

With respect to overall performance and ammunition availability, here are the five best all-around cartridges for North American big-game species.

Despite its rarity today, we all owe the .450 Nitro Express a debt of gratitude for the simple fact that it established a ballistic formula upon which so many dangerous game hunters rely.

The .17 Hornet, son of the classic .22 Hornet, is a well-balanced design. Sharing the rimmed design of the parent case, it feeds nicely in a bolt-action repeating rifle, provides pinpoint accuracy and minimal recoil, and checks all the boxes for varmint hunting.

Just about every case shape imaginable has been modified to hold both 7mm and .30-caliber bullets, but it was gunwriter Layne Simpson who saw a gap in the lineup: there was no 7mm cartridge based on a full-length .375 H&H case. In 1979, Simpson took the excellent 8mm Remington Magnum and necked it down to hold 7mm bullets, giving his wildcat the name “Shooting Times Westerner.”

What makes a magnum? Does a magnum cartridge need to be belted? What are the advantages/disadvantages of both designs? Contributor Philip Massaro takes a closer look at each to help you make a more informed decision.

Despite an array of competitors being introduced since its 1944 debut, Weatherby’s original .30-caliber magnum cartridge is arguably still the best in class.
