SINCLAIR HEX STYLE BULLET COMPARATORS Reviews & Ratings

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.

Very handy, but the finish on the tool was a little rough. I did some light polishing to remove some tool marks and burrs. Excellent value however for the money and number of calipers you can use it for. I hate to really rate this a 4, but slightly disappointed with finish.

Simple, well made piece.

I have used this tool for a few years and can say it's a very high quality unit. It's stainless so there's no concern about rust/pitting. I do think they should add another facet with .204.
