Hornady 7pce Bullet Comparator Set

Product Description

The Hornady 7pce Bullet Comparator Set is a precision reloading tool for measuring bullets and loaded cartridges from the ogive rather than the bullet tip. It combines a Lock-N-Load Bullet Comparator body with seven interchangeable inserts for common rifle bullet diameters.

Because bullet tips can vary in shape and length, ogive measurement provides a more consistent reference point. As a result, reloaders can compare bullets and loaded rounds more reliably when checking seating depth and developing loads.

Hornady 7pce Bullet Comparator Set Features

The Hornady 7pce Bullet Comparator Set attaches to a compatible caliper. The selected insert contacts the bullet ogive, while the caliper provides the measurement.

Furthermore, the interchangeable insert system allows one comparator body to measure several bullet diameters. The supplied inserts cover .224″, .243″, .257″, .264″, .277″, .284″ and .308″ bullets.

Consequently, this 7-piece comparator set suits reloaders who work with several common rifle calibres. In addition, the same measurement method can be used when comparing bullets within the same calibre.

Hornady 7pce Bullet Comparator Set for Ogive Measurement

Measuring cartridge overall length from the bullet tip can introduce variation because projectile tips are not always identical. The comparator instead establishes the measurement from the ogive, which provides a more consistent reference.

Therefore, reloaders can use ogive measurements to compare seating-depth changes more accurately. In particular, this is useful when setting up a seating die or checking consistency between loaded rounds.

Moreover, the comparator can help check bullet uniformity from the base to the ogive.

Seven Bullet Comparator Inserts

The set includes seven interchangeable inserts:

• .224″ / 5.56mm
• .243″ / 6mm
• .257″
• .264″ / 6.5mm
• .277″
• .284″ / 7mm
• .308″ / 7.62mm and 8mm

Therefore, the set covers a broad range of commonly used rifle bullet diameters without requiring a separate comparator body for each calibre.

As a result, reloaders can use one comparator body across several common rifle cartridges. Additionally, the interchangeable design allows further measurement options when compatible inserts are added.

Hornady 7pce Bullet Comparator Set Compatibility

The comparator works with a compatible caliper and can also be used with the Hornady Lock-N-Load O.A.L. Gauge. When used together, these tools allow reloaders to compare loads while establishing bullet seating depth for a selected amount of bullet free travel or jump.

Consequently, the comparator body forms part of a broader precision-measuring system rather than functioning as a standalone gauge.

Precision Reloading Applications

This 7-piece bullet comparator suits reloaders who want a repeatable reference when checking bullet seating depth, comparing loaded ammunition or examining bullet uniformity.

Moreover, the seven included inserts make the set practical for reloaders working across several rifle calibres. At the same time, ogive-based measurement reduces the influence of variations at the bullet tip.
