.223 full size guage - Lyman Rifle Case Length Headspace Gauges

Replicates the chamber of a .223 SAMMI. I thought my loads were good...OAL was dead on, at the ogive dead on. Full length resized...then I testes a 100 final loads and found about 10 where the shoulder wasn't in spec. These were ONCE fired so I pulled them and resized them...still out of spec...so in the recycle bin they went. Its nice to have this guage to check the final loads.
Pros: Simple to use, easy to read
Cons: none
