The History of Kimber

Kimber Manufacturing was founded in 1979 by Jack Warne in Clackamas, Oregon. Previously, Warne had established Sporting Arms (Sportco) in Adelaide, Australia, after WWII, and later moved to Oregon in 1968 when Omar Industries acquired his company. Initially, Kimber of Oregon focused on producing dependable .22 LR rifles, later expanding to centerfire rifles, pistols, and eventually revolvers.

In the 1990s, several Kimber employees left the company to form Cooper Firearms of Montana, while Jack Warne founded Warne Manufacturing in 1991, specializing in scope mounting systems. Kimber of Oregon was eventually sold to Bruce Engel, and in the 1990s, Greg Warne and Les Edelman, owner of Nationwide Sports Distributors, partnered to revive the company under the name Kimber of America.

Despite rapid expansion, Greg Warne was ousted when Edelman gained majority ownership. Edelman then merged Jerico Precision's manufacturing capabilities with Kimber's dealer network, relocating production to New York and establishing the company's presence in New York and New Jersey. Over the years, Kimber has developed a variety of firearms, including pistols, rifles, and revolvers, as well as manufacturing accessories to complement their products.

Some popular pistol models include the R7 Mako, EVO SP, MICRO series, California Compliant, and Massachusetts Compliant, among others. Kimber's rifles are available in four action designs: Model 84M, Model 84L, Model 8400 WSM, and Model 8400 Magnum. The early Kimber Model 82 rifle was a predecessor to the Model 84 action series. Revolvers are offered in DASA, Stainless, DCR variants, and special editions. On October 21, 2020, Kimber announced the relocation of its corporate headquarters to Troy, Alabama.

Kimber 8400 Magnum Rifle Review

The Kimber 8400 Magnum is a bolt-action centerfire rifle that was introduced in 2009. Prior to this, the Model 8400 was only manufactured with a short action suitable for the Winchester Short Magnums (Model 8400 WSM). However, the new 8400 Magnum action has the same diameter as the 8400 WSM but has been extended by 23.4 mm to accommodate longer calibers.

The rifle features a free-floated barrel and a three-position safety lever that is placed on the rear end of the receiver. The bolt is locked, and a cartridge cannot be removed when the safety is in the full rearward position. 8400 Magnum comes with a Match-grade trigger mechanism that is factory preset at a pull weight of approximately 1587 g (3.5 lbs).

The bolt of the Kimber 8400 Magnum has two opposing locking lugs and a Mauser-style claw extractor. Both wooden and polymer stocks are available, depending on the variant. Sling swivel studs come preinstalled, and the top of the receiver is drilled and tapped for scope mounting purposes. The magazine has a capacity of 5 rounds, except for magnum chamberings which have a capacity of 4 rounds. The magazine release button is positioned on the inside of the trigger guard, and the floorplate is made of steel.
