The Sinclair Bullet Comparator inserts are meant to be used with the Sinclair Bullet Comparator and Bump Gage Body. These 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 and compare bullet ogive-to-base as well as loaded round ogive-to-cartridge-base measurements. This measurement gives more consistent results than measuring overall lengths since the meplat (the open tip of the bullet) can very by several thousandths of an inch from bullet to bullet.

Top takeaways

  1. The Sinclair Bullet Comparator Inserts are designed to fit the Sinclair Bullet Comparator and Bump Gage Body, providing precise measurements for .375 caliber bullets.
  2. Made of stainless steel with a tapered and straight section, they offer an improved design over standard drilled holes, reducing wobble and increasing accuracy.
  3. These inserts allow for consistent measurement of bullet ogive-to-base and loaded round ogive-to-cartridge-base, which is more reliable than measuring overall length due to variations in meplat.
