Here's a visual of how little contact a new bolt can have in a Lee-Enfield. This is a NOS bolt body without any fitting done in a 1911 SMLE I obtained without bolt.
Just a small portion of one lug is bearing on the locking surface. Not good!
A good example of why it is so important to make sure that the bolt and body are properly 'matched' together
Mine are not the best, but they are not too bad. I can think of lots of Enfields I'd rather have but instead of constantly striving for more, sometimes it's good to be satisfied with what one has...
