Fitting Rifle Bolts

[gc1054]

All,
Question wrt fitting rifle bolts (No1s in my case...but could be No4, 5...etc.):
When fitting a replacement bolt and checking for equal bearing of the bolt recoil lugs (using eng blue, etc) in the body and say the right side (long lug) is bearing evenly (exercise bolt...blue nicely & evenly removed from lug surface) but the left side lug shows no evidence of bearing (eng blue unmarked), how far can you stone/adjust the bearing lug until the other lug (in this case the left or body lug) starts to bear? Can you incrementally go through the fitting process (stone...blue...re-check) and stone one, two, or a few thou off the lug that is bearing? Key part of question.....is there a point in the process where you need to stop (say at three thou for example) and investigate for other problems?
Thanks!

PS: I've read Peter L's Bolt Fitting articles many times and have successfully fitted a couple of bolts so far that didn't need much tweaking What I'm looking for is advice or info & some means (dim check, etc) of determining when to stop tweaking Also, I thought Bruce_in_Oz posted about bolt & body recoil lug absolute and relative dimensions and associated tolerances but for the life of me I cannot find it. Any helpin finding this info would be appreciated:}
