One cool feature of these 6″ SE calipers is that you can instantly switch between Metric and SAE (English) display. These asian-made calipers are hardly Mitutoyo quality, but we’ve used them and they work fine for most tasks: measuring neck diameters, Cartridge OAL, bullet diameters, and even the group sizes on your targets.

Note: The vast majority of customers who have purchased these calipers have rated them highly for the price. However a few buyers complained that the display was faulty. The unit we used worked fine and measurements were consistent with a $25.00 Lyman dial caliper. But if you want a serious “last a lifetime” set of calipers, you’ll want to spend more than $10.50 obviously. We see these as an inexpensive alternative for a “back-up” set to be kept in a vehicle or tool kit.
