.280 Ackley Improved
The .280 Ackley Improved (.280 AI) was the result of the .280 Remington case modification by P.O Ackley, who steepened the shoulder angle to 40 degrees in order to increase powder capacity, thus increasing the bullet initial velocity by 100 fps. History In 1957 Remington introduced the .280 Remington, which was based on the .30-06 Springfield case necked down to 7mm. The cartridge was intended to compete with the .30-06 and the .270 Winchester. Although the .280 Remington is considered to be a very balanced cartridge combining the best attributes of both cartridges due to the high ballistic coefficient and sectional density characteristic of 7mm calibers, it did not reach the popularity achieved by the .30-06 and .270 Win. The famous wildcatter P.O Ackley worked on the .280 Remington case in order to add it to the line of "Ackley Improved" cartridges and named it the .280 Ackley Improved 40 degrees. By 2008, Nosler standardized it and SAAMI accepted it. Ever since, the .280 ...

280 Remington
The ''.280 Remington'', also known as the 7mm-06 Remington and 7mm Express Remington, was introduced in 1957 for the Remington model 740, 760, 721, and 725 rifles. History Having been released 32 years after the .270 Winchester, it had somewhat unspectacular sales. Remington renamed the cartridge in late 1978 to 7mm-06 Remington. but just before the end of the year, they renamed it again, calling it the 7 mm Express in an attempt to increase sales. This resulted in people confusing it with the 7 mm Remington Magnum, and Remington changed the name back to .280 in 1981.The Versatile 280 at Outdoor Life

30-06 Springfield
The .30-06 Springfield cartridge (pronounced "thirty-aught-six" ), 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. The ".30" refers to the caliber of the bullet in inches. The "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. It remains a very popular sporting round, with ammunition produced by all major manufacturers. History In the early-1890s, the U.S. military adopted the smokeless powder .30-40 Krag rimmed cartridge. The 1894 version of that cartridge used a round-nose bullet. Around 1901, the U.S. started developing an experimental rimles ...

As the .280 Remington, and the .30-06 Springfield, the .270 Winchester derived from the .30-03 parent case and the bore diameter was likely inspired by 7mm Mauser.

History Introduced in 1925 along with the Winchester Model 54 bolt action rifle under the name "270 WCF" (270 Winchester Centerfire), the .270 Winchester was not an immediate success due to the popularity of the relatively recently introduced .30-06 Springfield, chambered for the M1903 Springfield bolt ...

Ruger M77
The Ruger M77 is a bolt-action rifle produced by Sturm, Ruger & Company. It was designed by Jim Sullivan during his three years with Ruger. The rifle features a traditional Mauser-style two-lugged bolt with a claw extractor. Design and features From the beginning, the Ruger M77 was intended as a modernized Mauser 98, though numerous changes were made. Bill Ruger wanted to use investment casting in place of a forged receiver. The Sullivan-designed bolt dispensed with the Mauser blade type ejector and instead used the simpler plunger style of ejector. A two-position tang safety and redesigned trigger system were also designed from scratch. Perhaps the most novel feature of the M77 is the only one that has not been redesigned, the angled action screw. The front action screw of traditional bolt-action rifles draws the receiver directly down against the stock. The M77 uses an angled screw that draws the action down and to the rear, tightly bedding it against the stock. Variant ...

The Savage Model 110 is a bolt-action repeating rifle made by Savage Arms. It was designed in 1958 by Nicholas L. Brewer. It was patented in 1963. The Model 110 has been in continuous production since that time. History The Model 110 was developed to give the hunters a strong and powerful yet light and affordable rifle. Its model number is derived from its initial retail price of $109.95. It was originally made for .30-06 Springfield and .270 Winchester ammunition. In 1959, a short-action version was introduced, chambered in .243 Winchester and .308 Winchester. The same year, the Model 110 was the first commercial bolt-action rifle sold in a left-handed configuration. In 1966, the Model 110's design was altered to improve performance and reduce production costs. Changes included a new adjustable trigger and a new bolt with a plunger-type ejector passing through the bolt face rather than the magazine-mounted, spring-loaded ejector that was part of Brewer's original design.

Weatherby Mark V
The Weatherby Mark V is a centerfire, bolt-action rifle manufactured by Weatherby of Sheridan, Wyoming. The rifle was introduced in 1957 by Weatherby and was designed to safely contain the high pressures associated with the Weatherby line of high performance cartridges. It is the flagship rifle of the Weatherby line of firearms. The Weatherby Mark V rifles are considered prestigious or luxury firearms by many. This is due in part to Roy Weatherby who presented the rifles to royalty, politicians, gun writers and actors including Prince Abdorreza Pahlavi of Iran, Generals James Doolittle (USAF) and Chuck Yeager (USAF), Jack O'Connor, Warren Page, Elgin Gates and Lorne Greene and was able to use this fact as a marketing tool. Early development Ever since Roy Weatherby began manufacturing rifles he had to rely on a third party to provide the actions for his rifles. Beginning in 1949 Weatherby began building his rifles around the FN Belgian Mauser action. In 1955 Schultz & Lars ...

7mm Remington Magnum
The 7mm Remington Magnum rifle cartridge was introduced as a commercially available round in 1962, along with the new Remington Model 700 bolt-action rifle. It is a member of the belted magnum family that is directly derived from the venerable .375 H&H Magnum.Speer Reloading Manual The original purpose of the belted magnum concept taken from the .300 H&H Magnum and .375 H&H Magnum, was to provide precise headspace control, since the sloping shoulders, while easing cartridge extraction, were unsuitable for this purpose. Improved cartridge extraction reliability is desirable while hunting dangerous game, in particular when a fast follow-up shot is required. The 7mm Remington Magnum is based on the commercial .264 Winchester Magnum, .338 Winchester Magnum, and .458 Winchester Magnum, which were based on the same belted .300 H&H Magnum and .375 H&H Magnum cases, trimmed to nearly the same length as the .270 Weatherby Magnum. History On its introduction, the 7mm Remington Magnu ...
