On my hunt for info on breaking in a new barrel which I was told you must do, I saw this video from an American gent who obviously knows lots about firearms, and his explanation makes a lot of sense. Do yourselves a favour and set the playback speed to x1.5 or x1.75 to save a little time... it's a long'un. He has heaps of very informative and very enjoyable vids on all sorts of topics - some good ones on improving accuracy too... which may be relevant here. Enjoy!

Watched some listened to some. Re barrel break in he reckons because copper is softer than steel copper cannot smooth the machining marks in the barrel. But copper at 3000 fps is going to behave quite differently to a piece siting on a work bench. Heck water can cut steel when it moves fast enough !
