Hornady Lock-N-Load Bullet Comparator
Comparator Inserts are designed for use with the Lock-N-Load Comparator; it eliminates variables when measuring the over-all length.
Length can vary a few thousandths due to material variation and tip finish.
The Lock-N-Load Comparator Inserts allow the user to measure from the base to a specific point on the ogive, which has little variation, if any.
This versatile system also provides the user with a much more consistent way to monitor the overall length, allowing the user to build more precision into their loads.
