Chamber Gauge ?

[B. Dudley]

Just buy the brass CSMC gauge and be done with it. It works, it gives you all gauges and is reasonably priced.
The only thing on it that may not always be accurate is the choke gauge.

thanks for the rapid reply! My only personal problems with getting the brass gauge are I don’t see myself ever needing to do this again, and I’d like to shoot this weekend. My concern with the steel socket was damaging something, but I was gentle.
