Barrel break in ???

[acemisser]

Barrel break-in = total myth and waste of ammunition and cleaning supplies.

Shoot it until the barrel fouls and the groups open up, clean, repeat.

I doubt it is a myth..I see lots of bench rest shooters clean after a 10 shot relay,so there is something to it weather
you think or not..I was told that I would be lucky to get 1000 rounds thru my 22-250....After talking to some barrel
makers and cleaning it as they suggested...No wire brush,solvent or foam cleaner and patchs.I am now going on
a total of 1475 to date...So there is something to it...
