The #1420 Bullet Comparator Insert (.204 calibre) is a precision-machined tool designed for reloaders seeking the highest level of accuracy with the .204 Ruger and other cartridges using .204 diameter bullets. Essential for anyone serious about precision shooting, this insert works with the Bullet Comparator system to deliver consistent, repeatable measurements that directly enhance rifle performance in the field or at the range.

When paired with a standard caliper and the main comparator body (sold separately), the insert allows reloaders to measure cartridge length from base to ogive—eliminating unreliable bullet tip variations. By focusing on the ogive, the most uniform point on a bullet, it ensures precise Cartridge Base To Ogive (CBTO) consistency for every round. This is critical for achieving uniform seating depth, reducing velocity spreads, and improving long-range accuracy—ideal for hunters and competitive shooters across Australia.

Additionally, the #1420 insert helps determine the exact “jump to lands” distance between bullet and rifling, a key variable in fine-tuning loads for optimal performance. It also serves as a quick bullet uniformity check, allowing reloaders to identify out-of-spec projectiles before heading into the field.

Built for precision and reliability, this insert is a must-have addition to any serious reloader’s kit.
