[QUOTE="Offgridkid, post: 829990, member: 44524"] Ok, sorry for this less than exciting topic, but I just can't seem to find the answer anywhere. Background: I have a full machine shop (metal working has been a hobby of mine for years). I have watched all of the key AGI videos, i have successfully blueprinted my action and have just received my first go no-go gauges. After reassembling my rem 700 (5R) i checked the headspace and find that the bolt closes very easily on the no go gauge. Before anyone asks I can say that i only had to take of a couple "thou" to get the action and bolt trued up, no biggy there, was pretty close to true as is. I have probably only fired 300 rounds through the rifle (bought new). I want to put a new thicker lug (already purchased) on it and that means pushing back the barrel (not sure of what the official name of the part that the existing lug sits on is called, but that is the area I am referring to). My question (finally right. . . .) is this, can i simply shorten the action side of the barrel a few thou at a time until my no-go gauge won't allow the bolt to close without reaming the barrel? I realize that there is a given depth between the outermost part of the barrel and the face that the bolt approaches, I can turn that down as well to keep that dimension as it is now. I was just hoping to not purchase a reamer if not needed and given that i need to shorten the headspace why would any reaming need to take place. I hope I explained this question well, if not, maybe someone could point me to a place that labels all of the surfaces of a bolt and barrel so I can use appropriate labels in explaining things thanks all [/QUOTE]
