What is the SINCLAIR INTERNATIONAL - Hex Style Bullet Comparator #1 22-30 Caliber?
Sinclair has been making these hex style bullet comparators for over 20 years. The holes in the Sinclair Bullet Comparators are cut with throating reamers to accurately duplicate the actual throat of a rifle. The comparator is used with calipers and allows the reloader to accurately measure the length from the major diameter of the bullet to the case head. It also enables you to make accurate seating depth changes to your bullet seater.


The Sinclair Comparator does not attach to your calipers, so your calipers are free for other measurements. Machined from stainless steel. There are two different models of Sinclair Comparators to cover bullets calibers from .17 caliber to .338.


SPECS
  • Hex Model #1 has holes bored and throated for 22 Caliber (0.224”), 6mm (0.243”), 25 Caliber (0.257”), 6.5mm (0.264”), 7mm (0.284”), and 30 Caliber (0.308”)
  • Hex Model #2 has holes bored and throated for 17 Caliber (0.172”), 20 Caliber (0.204”), 22 Caliber (0.224”), 270 Caliber (0.270”), 30 Caliber (0.308”) and 338 Caliber (0.338”)

Simple and versatile
I bought this to measure to ogive on my reloads, a much better system of adjusting bullet depth than overall length to the tip of the bullet. Once you have assembled a cartridge with the ideal bullet seating depth for your specific rifle, use that cartridge with this tool and a good set of calipers to measure, then save that information for all future reloads using that specific bullet for that specific rifle. It also allows measurement of six different bullet diameters.

Great tool to have
Great to use when adjusting seating depth. My only wish is that instead of duplicating the 30 caliber on this tool, a .35 caliber would have been added.
