Sorry I should have specified. This is a new build with a blank barrel. I am reaming the chamber to length, I want to load out to about 1.16 or so. I have a dummy round and will keep checking as I go but want to check and see what the actual measurement calls for. I understand cases are going to vary and I want to allow for the differences.
I am ready to ream my 9mm barrel and am having trouble finding the exact dimensions of the measurement from the barrel hood to the ridge. Is it .754”. What are most open 9mm builds set too?
Send it to black nitrite, They are fast and reasonably priced, they do have a minimum order so if you can find a couple guys that want to refinish their guns it works best to send at least two or three off at once.
