Hornady Bullet Comparator Insert 243/6mm LNL24 #324

For use with the Lock-N-Load Bullet Comparator, Bullet Comparator Inserts are created; this eliminates variables when determining the overall length of a bullet. Due to material variance and tip quality, bullet length can vary by a few thousandths. The reloader can measure the bullet from the base to a particular position on the ogive, which has minimal to no change, using the Lock-N-Load Bullet Comparator Inserts. The reloader can add more precision to their hand loads with the help of this flexible system, which results in better groups at the range and more meat in the freezer. It also gives the reloader a far more reliable way to track the overall length of their reloads. Specifically made for the Lock-N-Load (LNL) 24 (.243/6mm), this comparator insert.
