  • 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 caliper with the screw through the thicker leg of the body. This allows the proper off center alignment of the Length Gauge

If you want to get your reloading to a better level this tool and the overall length gauge are the way to go. Measurements to the ogive give you better consistency in your loads and the tool is very easy to use. Works great and is worth the money spent.

If your used to reloading or measuring with a caliper, this tool will not be difficult to use. I have been using it for 6 months and can give a thorough review. The comparator is well made, and the inserts are also solid. With frequent use, it does not show signs of wear. I expect this will last forever if taken care of. The more consistent you can make your rounds the more accurate you will be. There are deviations in bullet length, and this alleviates them by going off the ogive of the bullet. This is a must have if accuracy is your goal at the range.

A load comparator set allows you to get an accurate measurement of your actual rifle round from the base to the ogive of the bullethead, which is more accurate than just measuring the OAL of the round. Due to inconsistencies in bullet head manufacturing you will find differences. By measuring to the ogive and then reloading your bullets using that measurement and the actual chamber measurements of your rifle, you can get a consistent reload with more stable ogive to lands measurements which will improve your accuracy.To do this you need a few tools.The OAL gauge connects to a modified case and allows you to measure the chamber specs of your rifle. You then use those measurements to accurately figure out your riflers preference for your reloaded rounds. The bullets jump to the rifle lands is a very important calculation for accuracy. Too short and the bullet can cock or angle which causes inaccuracy. Too long and the bullet can contact the the lands when fired which can increase pressure in the case which is not only dangerous, but leads to inaccuracy and also an increase in pressure is also not good if you plan on using your cases multiple times.The whole set up for these measurements cost less than $100. The OAL length gauge, an anvil base, comparator set and inserts, headspace gauge kit, and some modified cases in the caliber you need will get you going. You will also need to connect these to your dial calipers, which if you are reloading your own ammo you should already have dial calipers.Is all this really needed? No. You can use a reload manual and get a decent round. If you are really looking for accuracy you can then make different loads in different lengths, and eventually arrive at the same place. But how many rounds did you have to go through for each load before you found nirvana with your load? 10? 50? 75? And this needs to be done for every bullet weight and profile, for each of your rifles. At around $1 a load, this equipment easily pays for itself in bullet development.
