Hornady L&L Anvil Base Kit
Product Description
The Hornady L&L Anvil Base Kit is an accessory for calipers used with the Hornady Lock-N-Load Comparator system. The anvil attaches to the opposite caliper blade and provides a larger, stable surface for supporting case heads and bullets during measurement.
As a result, the setup makes ogive and headspace measurements easier to obtain. The anvil is particularly useful when comparing loaded ammunition or measuring cartridge dimensions during precision reloading.
Hornady L&L Anvil Base Kit Features
The Hornady L&L Anvil Base Kit attaches directly to the opposite blade of a compatible caliper. Its larger contact surface supports the case head or bullet while the comparator performs the measurement.
Furthermore, the anvil helps keep the cartridge or bullet properly supported between the caliper jaws. This makes measurements easier to repeat when checking loaded ammunition.
The modular design works with the Hornady Lock-N-Load Comparator system. Therefore, it complements the comparator body and its interchangeable measurement inserts.
Hornady L&L Anvil Base Kit for Ogive Measurement
The anvil provides a stable support point when measuring from the bullet ogive. This is useful because measuring from the bullet tip can produce inconsistent results when projectile tips vary in shape or length.
Consequently, the comparator can provide a more consistent reference when checking bullet seating depth and comparing loaded rounds.
Headspace Measurement Support
The anvil also supports headspace measurements when used with the appropriate Hornady Lock-N-Load Headspace Comparator components.
The larger surface gives case heads a stable resting point during measurement. As a result, reloaders can compare fired and resized cases when checking changes in case headspace.
This makes the anvil useful for both cartridge measurement and case-preparation work.
Hornady L&L Anvil Base Kit Compatibility
The anvil works with compatible calipers and the Hornady Lock-N-Load Comparator system. It does not accept comparator inserts itself. Instead, it provides the supporting surface while the comparator component performs the measurement.
Therefore, the correct comparator body, insert or headspace bushing must be selected separately according to the measurement required.
Precision Reloading Applications
This accessory suits reloaders who measure bullet seating depth, loaded-round consistency or case headspace. In addition, it provides a practical support surface when using the comparator on a standard caliper.
The system is especially useful when repeatable measurements matter during load development. Furthermore, using a stable reference point helps make comparisons between cartridges and cases easier.
