Kimber Advanced Tactical II 8400 .300 Win. Mag Rifle

Description

Picture this: you’re glassing a ridge at 800 yards, the wind is a constant whisper, and you need a rifle that’s a known quantity—a tool that doesn’t add variables to an already complex equation. You need precision you can trust, not just on paper, but when the pressure’s on. That’s the realm of the Kimber Advanced Tactical II 8400 .300 Win. Mag 27″ Barrel. It’s a purpose-built, long-range precision rifle designed for shooters who demand repeatable accuracy and rugged reliability without the custom shop price tag. Here’s the thing—it delivers serious capability right out of the box.

The Kimber Advanced Tactical II 8400 .300 Win. Mag 27″ Barrel is a bolt-action, long-range tactical rifle chambered in the potent .300 Winchester Magnum. It features a heavy-contour, 27-inch stainless steel barrel for maximum velocity, a fully adjustable match-grade trigger, and a rigid aluminum bedding block system housed in a synthetic stock. This rifle is engineered for consistent, sub-MOA accuracy and is ready for duty or competition use with minimal setup. At $3477.99, it occupies a compelling middle ground between factory rifles and full custom builds.

Let’s talk about where your money goes. The heart of this system is that long, cold-hammer-forged barrel. The 27-inch length is no accident—it allows the .300 Win. Mag cartridge to reach its full ballistic potential, squeezing out every last foot-per-second for a flatter trajectory and more energy downrange. This is critical for engaging distant targets where even a small drop or wind drift means a miss. The barrel is also fluted, which shaves off unneeded weight and improves cooling without sacrificing the rigidity needed for precision.

The action is where Kimber’s build quality shines. The 8400 action is a controlled-round feed design, renowned for its reliability and smooth operation. It sits in a rigid, fiberglass-reinforced synthetic stock with an aluminum bedding block. This system, often called a “mini-chassis,” ensures the action is secured consistently shot after shot, which is a major factor in maintaining accuracy. The adjustable match trigger is a standout, allowing you to fine-tune pull weight to your preference—a feature usually found on rifles costing much more.

Weighing in at approximately 9.5 lbs without optics, the Advanced Tactical II is substantial but manageable. The weight, combined with the effective muzzle brake, helps tame the considerable recoil of the .300 Win. Mag, making longer practice sessions more tolerable. The stock features an adjustable cheek piece and length of pull, so you can achieve a proper, repeatable cheek weld without needing a gunsmith. It’s a rifle that fits out of the box for most shooters, a key advantage for those wanting a ready-to-roll platform.

Pros: The rifle offers outstanding out-of-the-box accuracy potential. The adjustable stock and trigger provide a high degree of customization for a factory gun. The .300 Win. Mag chambering gives you legitimate 1000+ yard capability on steel or game. The build quality and features compare favorably to custom rifles at a significantly lower entry point.

Cons: The 27-inch barrel makes the rifle long and can be cumbersome in tight spaces or vehicles. Ammunition cost for .300 Win. Mag is high, which impacts practice budget. It’s a specialized tool; it’s overkill for whitetail at 100 yards.

So who is this rifle for? It’s for the disciplined long-range shooter, the backcountry hunter pursuing elk or mule deer across vast canyons, or the tactical competitor looking for a reliable, accurate rifle without a five-figure investment. It’s also a smart choice for a serious shooter who appreciates quality but needs to justify the cost against other options. If you’re stepping up from a standard hunting rifle or an entry-level .308 precision rig, the Kimber Advanced Tactical II represents a major leap in capability.

Frequently Asked Questions

Q: Is this rifle a good choice for a first long-range rifle?

A: It depends on your budget and commitment. The .300 Win. Mag has significant recoil and ammo cost, which can hinder fundamentals. For a first dedicated long-range rifle, a .308 Winchester or 6.5 Creedmoor is often recommended. However, if you are committed to the discipline and want the extended range, this is a superb, capable platform that will not hold you back.

Q: What optics and mounts work well with it?

A: You’ll want a high-quality, first-focal-plane scope with robust turrets. Brands like Vortex Razor HD Gen III, Nightforce ATACR, or Leupold Mark 5HD in the 5-25x or similar magnification range are excellent matches. For mounts, seek out a 20 or 30 MOA inclined base from a reputable maker like Badger Ordnance, Spuhr, or Nightforce to maximize your elevation adjustment for extreme distances.

Q: How does it compare to a custom-built rifle?

A: A true custom rifle built on an action like a Defiance or Bighorn will offer more personalization in every component and potentially slightly better accuracy. However, that path often starts at $5,000 before optics. The Kimber delivers 90-95% of the performance for significantly less money, with the warranty and convenience of a factory rifle. It’s a major value proposition.

If the combination of proven long-range ballistics, robust construction, and factory-ready features aligns with your shooting goals, the Kimber Advanced Tactical II 8400 is a compelling investment.
