Never seen barrel break in hurt anything... and not breaking in sure gave me a fouler barrel once....
Serious questions here........
How do you know not "breaking in" caused the barrel to be a fouler???
How do you know it wouldn't have been a fouler even if you had done your break in procedure??
If breaking in a barrel simply cleans up reamer marks left in the throat, wouldn't the fouler barrel have "broken in" eventually??? In other words, if it fouled because you didn't do the break in to smooth the throat, why did it continue to foul after you shot it enough to smooth the throat??
