Hornady Lock-N-Load Bullet Comparator Basic Set, Includes 7 Bullet Inserts – Quickly and Precisely Measure Loaded Rounds, Measures from Bullet Ogive – Reduce Round Variations – B234

  • Hornady Comparator Kit – The Hornady Lock-N-Load Bullet Comparator is perfect for the reloader looking to measure seating depth of loaded ammunition quickly and precisely. Measures from the bullet ogive to the base of the loaded round, to eliminate variation in seating depth. This basic set includes 7 bullet inserts.
  • Why Do You Need a Hornady Bullet Comparator – Measuring cartridge lengths across the bullet tips is not a reliable (or repeatable) method for measuring loaded rounds. It’s common for variations of up to .025” to exist from one round to the next.
  • Reliable Rounds – Our Bullet Comparator measures rounds from the ogive to provide consistent, precise measurements. You can also use it to check uniformity of bullets from base to ogive.
  • Easy Measuring – Our Bullet Comparator easily attaches to the blade of your caliper and uses interchangeable inserts (available in sizes from .17 caliber to .45 caliber) to measure from the bullet ogive.
  • Kit Includes – Comparator body and 7 comparator inserts for the following diameter bullets: 224, 243, 257, 264, 277, 284 and 308. Allen Wrench also included. Other inserts sold separately. To position the comparator with the Hornady Lock-N-Load Overall Length Gauge, install comparator body to the calipe....
