Kimber 8400 WSM

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 WSM Rifle Review

Kimber 8400 WSM is a bolt-action centerfire rifle that was introduced by Kimber in 2003. It is essentially the ‘short action’ version of the 8400 series but is only chambered for Winchester Short Magnum (WSM) cartridges.

The rifle features a free-floated 24-inch match-grade barrel and an action that is bedded on twin aluminum pillars. The action is of a Mauser type with a three-position safety lever positioned on the rear end of the receiver. When the safety is in the full rearward position, the bolt is locked and a cartridge cannot be removed.

On the top of the receiver, there are drilled and tapped holes for scope mounts. The bolt has two opposing locking lugs and a Mauser-style claw extractor. The match-grade trigger of the Kimber 8400 WSM is fully adjustable and is factory preset at approximately 1587 g (3.5 lbs).

Since only WSM cartridges can be used, the magazine capacity of the rifle is 3 rounds. Positioned on the inside of the trigger guard is the magazine release button. Additionally, the stock comes with sling swivel studs and a rubber recoil pad.

Depending on the model, the 8400 WSM may have traditional walnut stocks with a hand-rubbed oil finish and hand-cut checkering, or Kevlar-carbon fiber stocks for rugged mountain hunting.
