The Sinclair 6.5mm (.264") Bullet Comparator Inserts are designed to work with the Sinclair Bullet Comparator and Bump Gage Body for precise measurements.
These inserts are made from stainless steel and feature a tapered design that closely replicates the chamber throat, reducing wobble and increasing accuracy.
They enable consistent measurement of bullet ogive-to-base and loaded round ogive-to-cartridge-base, offering more reliable results than overall length measurements.
The 6.5mm Modular Headspace Comparator Bullet Insert requires a separately purchased Modular Headspace Comparator Body.
It features a unique 3.0 degree "lead angle" to measure the bullet's ogive consistently, emulating contact like a 6.5mm chambered barrel.
These bullet inserts are made from 17-4 Stainless Steel, providing accurate measurements for bullets and loaded ammunition.
