050806111639 The Sinclair Bullet Seating Depth Tool has been used for decades by handloaders seeking the most accuracy out of their rifles. Our newest model is made from one fourth inch ground and polished stainless steel with one end turned down for use with 17 and 20 caliber rifles and the other end used for 22 caliber and up. This tool helps you determine the length of a loaded round touching the rifling. The Sinclair Seating Depth Tool will work with most bolt action, single shot and AR type rifles. The tool includes a Delrin action 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 uses your fireformed brass and bullets so you can expect an exact measurement, every time. Also available are guides use in AR-15's, AR-10's, and Tubb's 2000's. The guide is a little different than our standard bolt-action guides. This guide inserts into the back of the upper receiver (with the bolt removed). The tool is then used as normal. For best results couple this tool with our Bullet Comparators and a good set of calipers to get repeatable and precise Base-To-Ogive measurements.

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.

Brownells USA Money well spent 29/04/2017

This product is simple and made from good materials. The first time I used it I shot a 0.165" group at 100 yards. That's pretty good for a 35 caliber hunting rifle. My load development consisted of seven rounds. Two charge weights. One fouler. Two three shot groups. The second group was money.

Definitely recommended

Brownells USA Works great! 18/12/2013

I bought this to use on my AR-10 and it worked just fine with 175g Sierra Match King BTHP bullets. I also bought the AR-10 insert. I will be using this on my new bolt gun to achieve proper seating depth. Great product!
