Description

Hornady Bullet Comparator Insert 458cal 

Bullet comparator inserts are compatible with the Lock-N-Load Bullet Comparator. When measuring the overall length of a bullet, they reduce variations and allow the reloader to measure the bullet from the base to a consistent point on the ogive. This adaptable approach also allows reloaders to monitor the total length of their reloads in a more consistent manner, allowing them to put more precision into their handloads. This equates to more meat in the freezer and better groups at the range.

Additional Information:

Caliber: 45cal

Best Suited For

  • Reloaders working with .458 calibre projectiles (e.g. .458 SOCOM, .45-70 Gov’t)
  • Precision shooters needing consistent seating depth measurements
  • Handloaders aiming to optimise accuracy via bullet jump control
  • Users of the Hornady Lock-N-Load Bullet Comparator system

When To Use It

  • When setting bullet seating depth during reloading
  • To measure Cartridge Base To Ogive (CBTO) instead of unreliable tip length
  • During load development, ensuring consistent bullet positioning
  • When comparing different loads for accuracy tuning and repeatability

Unlike measuring overall length (OAL) from bullet tips—which can vary significantly—the comparator measures from the ogive, providing far more consistent readings.

FAQs

Q: What calibres does the .458 insert support?
A: Any .458 diameter projectile, including .458 SOCOM and .45-70 bullets.

Q: Do I need the full comparator kit?
A: Yes—you need the Hornady comparator body; this is just the insert.

Q: Why not measure overall length (OAL)?
A: Bullet tips vary; measuring from the ogive is far more consistent and precise.

Q: Is this useful for pistol calibres?
A: Generally less critical; comparator tools are mainly used for rifle precision reloading (community consensus).

Q: Can it improve accuracy?
A: Yes—consistent seating depth helps optimise bullet jump to rifling, a key accuracy factor.
