I finished a couple of new barrels---22-250---and have shot both a few times, both
appeared to be good shooters.
In the meanwhile I bought a Lyman bore scope and have found scratches in both
barrels-----top of the lands in the throat area----only.
I originally thought this had occurred when reaming the chambers but now am pretty
much convinced I did it twirling a bore brush to clean out in front of the chamber neck.
I have another barrel which will be rechambered so I decided to repeat the twirling on this chamber.
Scratched it also----convinced me that I caused the problem with a bronze bore brush. I don't have time to spend figuring how bronze will scratch stainless-----just want to move on to the correction
of this problem.
I'm sure I can remove these scratches by reaming the chamber a bit deeper----and correcting the tenon and headspace. This wouldn't be new to me but I'd like to avoid, if possible, the extra work.
Anybody here have an easier solution for this ?
Will appreciate any ideas on this.
