Introduced in the mid-1940s, the 7mm Weatherby Magnum case has minimal taper, maximizing powder capacity, and the correlative muzzle velocities show Roy Weatherby’s penchant for speed. Anything the popular 7mm Rem. Mag. will do, the 7mm Weatherby will do just a bit faster.
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.
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.
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.”
Winchester and Browning have collaborated to produce the 6.8 Western—a new take on the concept of the .270 WSM, using heavier bullets and a faster twist rate than previous iterations of the Winchester cartridges have used. Essentially, the 6.8 Western picks up where the .270 WSM leaves off, and delivers a whole lot more.
Undoubtedly one of our nation’s favorite cartridges, the .223 Remington is capable of hair-splitting accuracy in a properly built rifle, has enough velocity for a respectable trajectory, and with the heavier bullets with a higher BC, can resist wind deflection rather well.
