For over 20 years, Sinclair has manufactured hex-style bullet comparators. The holes in the Sinclair bullet comparators are precisely cut using throating reamers to accurately replicate the actual throat of a rifle. When used with calipers, the comparator allows the reloader to measure the length from the major diameter of the bullet to the case head with precision. Additionally, it facilitates accurate adjustments to the seating depth of the bullet seater.

Precision-engineered from high-grade stainless steel for optimal durability and corrosion resistance
