I would suggest the tree whack method is a gunsmithing myth
This book while only 65 pages is an absolute bible on making 303 service rifle barrels
It covers in ever stage and every machine in the process of making service rifle barrels in huge volumes
Even down to the multi story buildings for the cutting oil from dozens of machines to drain and be filtered to be pumped back to the machine rooms
There are many pages on barrel straightening and the hammer and block method is preferred to the machine method due to speed of experienced operators
This is a truly fascinating little book and I should make some copies
I expect there are some 303 tragics who would love a copy
