Parametric precision projectile propellers - ergonomic seating tools

The perfect companion for your bullet calibration block. It's tedious and inconsistent to manually calibrate hundreds of lead bullets through a calibration mold. This devicePrecision projectile propulsion deviceIt aims to provide comfortable and even pressure, ensuring that every bullet is perfectly and straightly seated without deforming the bullet skirt.

Main features

• Concave "cup-shaped" tip:The tip has a concave dome that allows it to position itself at the center of the projectile. This prevents the projectile from tilting sideways during the calibration process, which is the primary cause of deformation that leads to a decrease in accuracy.
• Anti-roll hexagonal handle:The 20-millimeter hexagonal base feels great to the touch, and more importantly, it prevents tools from rolling off your workbench.
• Quickly identify the base:The diameter size isImprintingThe method is engraved on the bottom of the handle. If you have multiple boosters for .177, .22, or .25, you can identify them at a glance.
• Optimize the length:The length of 65 mm provides enough clearance to push the projectile completely through the standard 15-mm to 20-mm calibration block.

Recommended printing settings

This tool can withstand significant vertical pressure. To extend its lifespan, please use the following settings:

• Materials:PETG or ASA。
• Number of walls:5 laps or more。
• Fill in:50%。Sturdy tools can better transfer energy and won't bend.
• Floor height:0.12 millimeters
• Brim:OptionalDue to the fact that the tool is tall and narrow, it is highly recommended to use a brim of 5 mm to 8 mm to ensure that it does not wobble during the printing process.
