SINCLAIR HEX STYLE BULLET COMPARATORS

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.

Bullet comparator
Excellent product…..well made and very useful for seating depth adjustments.

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 price!

A tool all hand loaders should have
These are a must to own when working with hand loads to get the proper seating depth.
5
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.
5
One of the best tools
This is one the best tools I have used for reloading. Fits at the diameter of the bullet so comparison measurements are true. Every precision reloader should have one.

Bullet comparator #1 review
2 friends and I have these for our 308s which we use for benchrest and FTR. Mine and one other have a chamfer at each hole. The third does not and bullets will measure .040 longer on that third one. You can even see that it does not come down as far on the bullet. They do provide you the ability to consistantly seat at the same depth, so you can use these for your own loads but dont use them to provide measuring data to someone else.

Simple but Great...
A very simple consistent tool. Have used it for years measuring my target rounds. Great for use with analog calipers.

100% satisfaction
I probably bought mine 20yrs ago. I use it every time I load for a rifle.And I measure factory loads with it... that reveals a lot about bullet shape and jump to the lands. Sinclair this comparator is as handy as the veneer calipers and it takes my reloading to a new level. Guy's and gals I gave this tool 5 * and I never do that.

Recommend
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.
