- You can sort questionable brass and confirm that resized cases and finished rounds work with typical SAAMI chambers, which reduces the need to test every batch in the firearm.
- As you dial in your sizing die and trimming process, this gauge provides a consistent standard so your 45 Auto reloads feed and function the way you expect in carry, training, or match pistols.
