Hand Loader! Are you looking for improved accuracy? Accuracy demands consistency and precision in every operation and component used in hand loading. The brass case is very important and sometimes important details are overlooked--such as the Primer Pocket and Flash Hole inside of the case.

In cartridge manufacturing, the flash hole is "punched" into the brass. While this is the least expensive method, it has many shortcomings and inconsistencies. The flash holes, therefore, are of different sizes and shapes. The most detrimental to accuracy are the irregular "breakouts" and "burrs" on the inside. This will cause "shot-to-shot" differences in Primer "Flame Fronts," causing inconsistent pressure/velocity and, thereby, loss of accuracy. Bench Rest Shooters have been uniforming flash holes since 1969.

With the Precision K & M UNIFORMER tools, you can realize the potential accuracy by simultaneously reaming, de-burring and chamfering the inside of the flash hole. The unique features of the K & M Tools provide uniformity with a pre-set depth stop, (Gage), surrounding the tool steel cutter, therefore, does not require the case to be trimmed to a precise or consistent length. Operation is controlled in reference to inside-bottom of case, not case mouth.

Ten Commandments

Set up your reloading bench where it (and stored components) will not be exposed to heat, sparks or flame.
Establish a comfortable loading procedure and don't vary it.
Keep your reloading bench, equipment and area clean and uncluttered. Label components and reloads for safe, easy identification. Never use powder from an unlabelled tin.
Understand what you are doing and why it must be done in a specific way.
Follow loading recommendations exactly. Don't substitute components for those listed in metallic data without reducing the load and working back up.
Never substitute smokeless powder for black powder or Pyrodex because smokeless powder is much more powerful than black powder. Never mix two powders together.
Wear safety glasses.
Stay alert when reloading. Don't reload when distracted, disoriented or tired.
Don't smoke, drink alcohol or take drugs while reloading or while in your reloading area.
Keep everything out of reach of small children.
