Re-crown or couter-bore?

[Richard Hare]

Morning gents,

Just wondering;
Was re-crowning or counter-boring ever done on British L-E's rifles to regain accuracy?
Some, like the Soviiet and Finnish M-Nagants were very often so treated, (apparently successfully) most of the time.
Was such a procedure ever used or part of the Armourers instructions?
Peter??
