The Sinclair Bullet Seating Depth Tool is crafted from polished stainless steel and designed for both small and large calibers, assisting in accurate loaded round lengths.
It is compatible with most bolt action, single shot, and AR type rifles, and comes with a Delrin action guide for a variety of popular bolt-action rifles.
For precise measurements, the tool uses fireformed brass and bullets, and can be paired with Bullet Comparators and calipers for consistent Base-To-Ogive measurements.
