The .338 Caliber Bullet Comparator Insert #933 is a must-have precision tool for reloaders who demand consistency and accuracy in their rifle ammunition. Designed for cartridges such as the .338 Lapua Magnum, .338 Winchester Magnum, and .338 Federal, this small interchangeable insert forms an essential part of the Bullet Comparator system used by serious shooters across Australia.

The #933 insert enables precise measurement of a cartridge’s length from the base to a consistent point on the bullet’s ogive—the curved transition between the shank and tip. When paired with a standard caliper and comparator body, it eliminates unreliable tip-to-tip measurements and ensures repeatable results. Eliminates Tip Variation by avoiding inconsistencies in bullet tips, delivers precision seating depth for uniform bullet placement, and helps determine the exact “jump” to the lands in your rifle’s chamber—critical for fine-tuning loads for maximum accuracy.

Ideal for precision shooters, hunters, and reloaders, this insert also serves as a bullet uniformity check tool, quickly identifying variations within a batch of .338 projectiles. Whether you’re setting up for long-range shooting, fine-tuning your hunting rifle, or testing new loads with your rifle scope and shooting optics, this comparator insert ensures unmatched consistency.
