The Lyman Drop Tube Lock Screw (Model: LY-DTLS) is a specialized, precision-engineered replacement component designed to secure the powder drop tube or funnel assembly firmly into the body of your Lyman powder measure. For Australian reloaders utilizing classic reloading setups, maintaining the structural integrity of your powder measure is critical for safety and volumetric accuracy. This micro-sized steel set screw directly replaces or upgrades older retention systems—such as the early spring steel clips—which were prone to developing play or wobble over time. By tightening directly against the drop tube, the LY-DTLS provides a completely rigid, movement-free connection, ensuring consistent powder drops and preventing accidental powder leakage or misalignment during high-volume reloading sessions on your bench.

Key Features of the Lyman Drop Tube Lock Screw:

• Precision Threading: Features a specialized 10-36 UNS thread pitch with an approximate outer diameter of 0.185 inches, ensuring a perfect factory-spec fit for compatible Lyman powder measures.
• Elimination of Play: Replaces loose-fitting spring clips to lock the drop tube securely to the powder measure body, eliminating any lateral movement or wobble during operation.
• Heavy-Duty Steel Construction: Manufactured from durable steel to withstand the repetitive vibrations, torque, and mechanical stress of manual reloading bench operations.
• Improved Reloading Consistency: By maintaining a rigid alignment between the measure and the drop tube, it prevents powder bridging and leakage, which is vital for precise charge weights.
• Australian Regulatory Compliance: As a purely mechanical, non-controlled reloading press spare part, this item does not require a Permit to Acquire (PTA) or specialized licensing under Australian state firearms regulations, allowing for hassle-free delivery nationwide.
