338L Match Grade 6-Piece Shellholder Kit by Derraco
Extreme precision for the ultimate long-range caliber
The 338L Match Grade Shellholder Kit from Derraco Engineering is specifically developed for the most demanding long-range caliber, the .338 Lapua Magnum. This set of six CNC-manufactured shellholders offers the absolute precision needed to harness the full potential of this legendary caliber.
Built for extreme loads
The .338 Lapua Magnum generates extreme pressure levels and accordingly requires robust tooling. These shellholders are manufactured from 420 stainless steel and hardened to 45-50 HRC, being tempered twice at 300 degrees for the optimal combination of hardness and toughness. The CNC machining ensures that the top and base of each shellholder are machined with one milling cutter, guaranteeing perfect parallelism.
Six incremental steps for perfect tuning
Unlike standard 5-piece sets, this Derraco kit contains six shellholders, including a "0" reference shellholder. The incremental differences of 0.002" (0.05mm) give you unprecedented control over the headspace of your reloaded ammunition. When working with .338 Lapua cases, which are already considerably more expensive per piece than standard calibers, this precision is essential to maximize the lifespan of your brass.
Suitable for the .338 Lapua family
This shellholder set is designed for the .338 Lapua Magnum and related calibers such as .300 Norma Magnum, .416 Rigby and other calibers with the same large rim diameter. It is shellholder #35 compatible according to industry standard numbering, meaning it fits perfectly with your existing dies and tooling.
Essential for ELR shooting
The .338 Lapua Magnum is the premier caliber for Extreme Long Range (ELR) precision shooting, where distances of 1500 meters and beyond are regularly engaged. At these distances, even the smallest inconsistencies in your ammunition are exponentially magnified. With this shellholder set, you can systematically determine the optimal headspace for your specific chamber, resulting in minimal ES and SD values.
Stainless steel construction
Unlike the carbon steel shellholders from some competitors, these Derraco shellholders are manufactured from stainless steel. This means they will not rust, even with prolonged use in humid conditions. For long-range shooters who often take their equipment to different locations and climates, this is a valuable advantage.
Precision sizing for competition ammunition
When loading .338 Lapua ammunition for King of 2 Mile competitions or other ELR matches, consistency is everything. These shellholders enable you to work your brass as minimally as possible, leading to better concentricity and longer brass life. By finding the perfect headspace that offers just enough clearance without unnecessary working, you maximize both precision and the number of reloading cycles.
