Holland's Bullet Comparator is used exclusively by Sierra Bullets to improve the quality control of Sierra's MatchKing bullets. Measure the following bullets, 0.224, 6mm, 6.5mm, 7mm, 30cal, and 0.338. This comparator allows the serious handloader to measure Base-to-OGive to +/- 0.0003 of an inch. This ensures perfect exit timing and uniformity of all MatchGrade and hunting bullets. Say goodbye to flyers due to inconsistent bullet lengths. The anti-skid base and precision V-block allows the shooter to process hundreds of bullets and hour. An All-American-Made Product!
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Makes it easy to sort bullets by base to ogive variance. Very easy to use and very accurate. I like that the bullet sleeves are included. Fast shipping. I'm happy!
