Bullet Comparator Insert 270 Calibre (0.277") Stainless Steel
This Bullet Comparator insert is meant to be used with the Hornady Comparator 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 simply have drilled holes.
This 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 vary by several thousandths of an inch from bullet to bullet.
Note: These inserts are not intended to measure rounds seated to magazine length or shorter.
Fits Hornady & Sinclair comparator bodies.
