I took the 1" piece I cut from the muzzle end and used the chamber reamer to cut myself a gage to aid in sizing brass and seating bullets. I zeroed my digital calipers over the gage and then trimmed the gage back to the datum to end up with the same 1.079 marked on the gage.
I can now zero my caliper over the gage and then measure brass for headspace and shoulder bump. The best part is when setting up a new bullet I'm able to set my OAL by dropping a long seated round and seeing how far I am from the shoulder touching and the 1.079 dimension. Then I can make adjustments and sneak right up to the length for my newly cut chamber.
Its not exactly a headspace gage or a case cage. So, what should I call it, a shoulder gage?
Lyman 311299, 311284 and 311466 set up using the new gage. I wish I had one for every rifle I own.
