Extreme precision reloading demands maximum consistency, and one of the easiest ways to do that, within reach an convenience for even standard reloading, is measuring the overall cartridge length using the bullet's ogive. Machining variances can result in the overall length of a bullet being different by several thousandths if measured from base to tip, which could give a false reading when seating bullets specifically for your rifle just a few thousandths off of the lands.
Bullet Comparator Inserts are designed for use with the Lock-N-Load Bullet Comparator; it elminates variables when measuring the over-all length of a bullet. Bullet length can vary a few thousandths due to material variation and tip finish. The Lock-N-Load Bullet Comparator Inserts allow the reloader to measure the bullet from the base to a specific point on the ogive, which has little variation, if any. This versatile system also provides the reloader with a much more consistent way to monitor the overall length of their reloads, allowing the reloader to build more precision into their handloads, that translates into better groups at the range and more meat in the freezer.
