Super Little Attachment

This anvil base makes all the headaches stay away while measuring OAL on reloaded cartridges. It makes it so easy even a first grader can line up the cartridge. Thank you so very much. HAPPY Reloader

Been reloading for years and recently purchased the anvil base ,I should have got this years ago! It gives me an accurate measurement whether I’m using it with the bullet comparator ,headspace comp, or just OAL. I have a couple now that I keep attached to my calipers.

Hornady Bullet Comparatore and Anvil

These are decent quality for the price and pretty much the only affordable alternative. They're a must for precision reloading, and make the bullet comparator much easier to use.

Must Have

By Robert H. on Oct 03, 2020
Must have this, makes for more consistent placement of the case head on a larger surface vs the caliper. More consistent placement of the casing shoulder is the result.... better repeatability.

This really helps getting the cartridge to center and get an accurate reading.

Hornady Anvil and Comparator body

By Thomas S. on Sep 03, 2019
The anvil is almost essential when using any of the comparators. it is much easier taking measurements when the base is on a stable platform. The setscrews provide to space the anvil to the micrometer aren't really needed. Just be sure the brass screws on the base and the comparator body face the same direction; alignment is perfect.

Great product, keeps base level.

My Thoughts

By Jeff T. on Feb 03, 2019
It's well made and simple. I'd consider it optional for the Hornady Bullet Comparator if you're one whose looking to conserve funds, but it makes for a more stable platform to place the case head on when taking measurements. I chose to purchase it out of curiosity.

Comparator anvil base kit

You really need these to get the most accurate measurements using the comparator body. Provides a stable platform for cartridge length measure.
