Bullet and Headspace Gauge Comparator Kit with 14 Inserts and 6 Bushings, Reloading Supplies and Equipment and Ammo Reloading Tool with Tin Box, Anodized Aluminum

I recently received the comparator set from Altitude Craft, and it’s a well-built, highly detailed tool for precision reloading. It’s as fully complete as any other set out there. I’m currently using it on both .223, 28nos, .30-06 and .300 Win Mag for checking chamber length and bullet seating depth. The storage box is compact and protective (something that other more expensive brands don’t include), the labeling is sharp and easy to read, and the color coding looks great while making organization simple. Functionally, everything worked perfectly. The set I received was slightly different than the product photos, but not in a way that affected use or quality. When I reached out to customer service, not to complain, but to see if I could get different set screw, they went above and beyond to help me out. Their responsiveness and willingness to assist really stood out. All in all, I’m extremely happy with this set. It’s clear that Altitude Craft cares about both their products and their customers.

Works well, and is consistent

ease of use size

good price , makes it easy to check bullet length for different bullet heads and easy to check shoulder length too. Great tool for reloading.

You'll need one of these kids if you really want to get precise with things like bullet seating for making match-grade ammo
