I am taking delivery of a new .308w this week and would like some advice on 'running in' a new barrel - it is really necessary with modern precision made barrels, or is this laborious process of '1 shot, clean; 1 shot, clean, 1 shot, clean' etc etc a conspiracy by the suppliers of barrel-cleaning materials?
Btw the rifle will be used for stalking, not for target shooting.
I would appreciate some views but only if they are backed up by facts (i.e. some evidence of tests/benchmarking) not just opinions based on thin air. Has anybody actually tested two brand new identical barrels, one run in using the above described process, one just used straight out of the box, and was there a noticeable (= measurable!) difference in accuracy?
