The Sinclair Bullet Seating Depth Tool: Precision for Every Handloader
The Sinclair Bullet Seating Depth Tool has been a trusted companion for handloaders for decades, ensuring maximum accuracy from their rifles. Our latest model features:
- Construction: Made from one fourth inch ground and polished stainless steel.
- Dual Ends: One end is designed for use with 17 and 20 caliber rifles, while the other accommodates 22 caliber and above.
- Measurement Capability: Helps determine the length of a loaded round touching the rifling.
- Compatibility: Works with most bolt action, single shot, and AR type rifles.
- Delrin Action Guide: Included guide suitable for most bolt-action rifles (0.690” Diameter fits Remingtons, Savages, Winchesters, and many Rugers).
For the most accurate measurement, the Sinclair Bullet Seating Depth Tool utilises your fireformed brass and bullets, ensuring precise results every time. Additionally, guides for AR-15's, AR-10's, and Tubb's 2000's are also available. This guide is slightly different from our standard bolt-action guides, as it inserts into the back of the upper receiver (with the bolt removed).
For optimal results, we recommend pairing this tool with our Bullet Comparators and a quality set of calipers to achieve repeatable and precise Base-To-Ogive measurements.
