K & M Precision Reloading

Philosophy: Consistency Above All

K&M's core philosophy is simple yet powerful: consistent ammunition delivers consistent results. Where other brands work with approximations and "feel-based" loading, K&M develops tools that guarantee measurable, repeatable precision. This approach has made K&M the trusted choice for benchrest shooters, F-Class competition shooters, and long-range precision shooters worldwide. Whether you're shooting at 300 meters or 1000 yards, K&M tools help you extract maximum accuracy from your equipment.

The K&M Arbor Press: Precision You Can Feel

The K&M arbor press has become an icon within the reloading world. This robust press, available in right and left-handed versions, is used with inline bullet seating dies and neck sizing dies from brands like L.E. Wilson and Short Action Customs. The unique toggle link system provides improved, smooth movement that gives essential tactile feedback during bullet seating.

What distinguishes the K&M arbor press is the ability to literally feel what's happening when a bullet is seated into the case neck. This sensitivity is crucial for achieving optimal consistency. The compact dimensions (base 3.5" x 5", height 11") make the press suitable for use both on your loading bench and at the range itself. Working height is adjustable from 0" to 7.5" (or 0" to 6" when used with a force pack), and can be easily adjusted with the included T-handle hex key.

The optional force packs add another dimension to your reloading process. With these spring packs and dial indicator, you can measure the exact force required to seat a bullet. This is incredibly valuable for monitoring neck tension across multiple cases. At each thousandth of an inch deflection, you measure 1 pound of force, enabling constant seating force and further improving consistency.

Hand Primer with Gauge: Revolutionary Primer Seating

The K&M hand primer with gauge represents a breakthrough in primer seating technology. Where other priming tools rely on feel or fixed stops, the K&M primer gauge is the only tool that directly shows how much primer crush you're achieving. This is possible because the system measures both primer height and pocket depth before the primer is seated.

The principle is elegant: you first measure the primer cup height, set the dial indicator to zero, then measure the primer pocket depth, and seat the primer to your desired crush depth (usually 0.002" to 0.003"). Because pocket depths vary, even after uniforming, and primer cup heights aren't identical either, this is the only way to guarantee truly consistent primer seating. Benchrest shooters and F-Class competition shooters report improvements in extreme spread (ES) of 4-5 fps after switching to the K&M system.

The tool comes with both large and small primer anvils and requires a separate shell holder chosen specifically for your caliber. While the process takes slightly more time per case than traditional priming tools, the consistency pays back directly in improved ignition uniformity and thus better velocities and accuracy.

Flashhole Uniformers: The Foundation of Consistent Ignition

K&M's flashhole uniformers are essential for serious reloaders. As described earlier, flashholes are industrially punched, leading to inconsistencies in shape, size, and especially burrs on the inside. These irregularities disrupt the primer flame front, resulting in shot-to-shot variations in pressure and velocity.

K&M uniformers are available in 0.080" (standard for most rifle and pistol calibers) and 0.062" (for PPC/BR calibers and small flashhole cases). What's unique about the K&M system is the integrated depth stop surrounding the hardened steel cutter. This ensures every flashhole is machined to exactly the same depth, regardless of case length variations. The tapered centering guide placed in the case mouth guarantees perfect centering. The tool reams, deburrs, and chamfers the flashhole in one movement at a 60-degree angle.

Case Neck Chamfer Tools: Smooth Bullet Seating Without Damage

K&M's controlled depth chamfer tools are developed with a specific goal: creating a shallow 4-degree chamfer that allows bullets to seat smoothly without damaging the bullet base. Traditional 45-degree chamfer tools create a much sharper surface that can potentially damage the heel of the bullet (the transition between base and bearing surface) during seating.

The K&M chamfer tool uses stop fingers that register on the case mouth, guaranteeing exactly the same chamfer depth on every case. A pilot pin goes through the flashhole and keeps the tool perfectly centered on the case axis, resulting in a completely uniform cut around the entire case mouth circumference. Users report less bullet runout with the K&M tool compared to conventional chamfer tools.

Typical chamfer depth is 0.015" to 0.030", and due to the sharp cutter, only 2 to 3 rotations with thumb and forefinger are sufficient. The result is a perfect, chatter-free chamfer that positions bullets precisely in the center of the case without neck distortion during seating. For larger volumes of cases, an optional power adapter is available with 1/4" drive for use with a cordless screwdriver.

Neck Turning Tools: Micro-Adjustable Precision

K&M's micro-adjustable neck turning tools are among the most advanced on the market. The system uses a unique "screw within a screw" concept with extra fine threads that provides 0.002" cutter advancement per full rotation of the adjustment nut. For comparison: a standard micrometer advancement is 0.025" per rotation.

The etched markers on the neck turner body are placed every 30 degrees radially, and with the reference punch mark on the adjustment nut, you can adjust the cutter in 0.0002" increments. This precision is essential for achieving exact neck wall thickness, which directly contributes to concentric bullet alignment.

The tools are available with tool steel or carbide cutters in calibers from .17 to .338 and even .50 BMG for large caliber shooters. The 50-degree cutter angle works with all shoulder angles and allows you to cut slightly into the neck/shoulder junction, preventing "doughnut" formation. The system can be used manually or with the power adapter and a cordless screwdriver for efficient work with large quantities of brass.

Accessories That Make the Difference

K&M offers an extensive range of accessories that further optimize the reloading process. The Pilot Jack for the neck turner makes setting the pilot position easier with a thumb screw that pushes against the pilot shank. The Ergo Holder significantly improves ergonomics when you're turning large quantities of brass and is essential when using a dial indicator for measuring wall thickness.

For the arbor press, force packs are available in low and standard versions, each with a spring pack and dial indicator for monitoring seating force. These packs provide real-time feedback during the bullet seating process and help you consistently maintain the same seating force.
