SINCLAIR INSERT STYLE BULLET COMPARATOR Reviews & Ratings

SINCLAIR INSERT STYLE BULLET COMPARATORS

This Sinclair Comparator is an excellent tool to use to sort bullets by base to give length. This is a valuable step if you are considering trimming the bullet meplat. NOTE: When sorting a lot of bullets, a digital caliper is sometimes a better choice for some handloaders than a dial caliper. An alternative tool to use for sorting bullets is our Sinclair Bullet Sorting Stand (#59-2000) which uses its own unique comparators. Our Sinclair Bullet Comparator attaches to the blade of your caliper and uses inserts for each specific caliber. The inserts are stainless steel and machined with a taper and a short straight section to more accurately duplicate the chamber throat. This eliminates the wobble experienced with many comparators which have standard drilled holes. Our design allows you to quickly and accurately measure the bullet's bearing surface of the bullet. Comparator inserts are available in 17 thru 45 caliber, and they can be used in both the Sinclair and older Stoney Point comparator bodies. These inserts are not intended to measure rounds seated to magazine length or shorter. For this application please see our Sinclair Bullet Comparators (#09-600 and #09-700).

Feels Like Plastic

I thought the product was made of metal, which is should be. Feels like plastic, which it should not be. I didn't have much luck with this product and the inserts using it as a bump gauge. The readings were inconsistent even with two different calipers. Even trying to bump .308 cases back 4/1000ths for an AR10 was nearly impossible to do with any consistency. The finished products did not shoot as well as a fully resized cases in the testing I did.

Requires honing geometry change

The tapered opening is right at .277 and goes extremely far down VLD type/Accubond bullets, this makes it impossible to measure Ogive Combined Overall Length on loaded bullets. The older stainless steel hexagonal shaped comparator is much more useful as it's tapered opening is at .268". This comparator insert's tapered opening should start at .270" within .001" of that.
