Reloading Equipment

Reloading Equipment
Working A Family Of Tools.

During a reloading session with the 10mm Auto, I ran across an interesting observation from the loading bench. We often hear the old adage from car companies to buy original equipment parts. Computer peripherals seem to work best when the same brand is applied, and a Nikon lens makes that Nikon camera do everything it should. In reloading equipment, the same basic reasoning holds true as well.

While American manufacturers of reloading equipment have a gentleman’s agreement on interoperability, advantages can be gained from working within a family of tools from one manufacturer. This allows for the unified engineering efforts of some very bright individuals in this industry using minimum tolerances, yielding maximum results from our components.

A bench supporting all of one manufacturer also eases the road to finding an answer when a kink in the loading process occurs. A customer service department having direct knowledge of all the tools involved can quickly diagnosis the dilemma. This is especially important in the matters of datum line headspace, as the contact of the shellholder against the bottom of the die sets this critical dimension. Each manufacturer has their own algorithms for determining just how much bump is needed based on caliber and brass spring-back to attain proper dimension to fit a minimum chamber.

The company will build their shellholder depth into this formula. This is not to say one shell-holder from another maker will not work with the dies of the other. However, with a tight chamber, a mismatched combination may not get you that last thousandth needed for the completed round to load properly. Expander buttons and straight wall case expander dies are another area where each manufacturer has their own beliefs on what constitutes proper size.

Consistency

Without diving deeply into technical discussions, Redding has made my life easier loading the 10mm Auto with their family of equipment. Take their heavy-duty turret T-7 reloading press for example, which limits handling and maintains a consistent setup. This style of press provides the strength and accuracy of a single stage press while allowing you to have seven dies set.

With the 10mm project, I had four Redding titanium carbide dies needed in the turret and went through the process, only handling the Starline cases two times. No die changes were needed. Not what you would call truly progressive, but truly precise, one-at-a-time loading. Powder dispensing was also precise with their Model 10X mounted in a Redding Bench Stand, then checked on a Redding 2400 powder and bullet scale. All the equipment compliments each other.

We all have our favorites in the field of reloading equipment. When searching for the most consistent and accurate loads possible, sticking with one brand may have advantages.
