What is the SINCLAIR INTERNATIONAL - Comparator & Bump Gauge Body, XL?

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).

works great not my first set

Works great not my first set I a set for 30BR reloading and a set for 6BR-Norma, along wiht other inserts. I find these are better than the other brand (L_N_L) due to the bevel on the ogive. There is nothing wrong with the L-N-L i have them and used them even before BIG H bought them. These are an improvment IMHO. Just do not mix the brands stay with one for you measurements until done same goes for Micrometers and calipers.

Would you recommend this? Yes, I would recommend to a friend

Exellant quality

A must have for precision reloaders and shooters! The other reviews about it being plastic are wrong. Its a solid piece of equipment, and with the correct caliber inserts will have your brass consistent throughout the whole batch.

Quality construction

The previous review about the item feeling like plastic is incorrect. The item feels like the usual billet aluminum it is constructed from. No issues whatsoever. Will definitely help with my seating depth.

Quality Construction

The bump gauge/comparator body has quality construction, and hold the inserts well. They attach to my calipers securely, and work well.
