Finally someone admitted that barrel break in is a hoax! I thought I was the only one!
For years all I did with a new barrel was run a f ew patchesd threw the barrel to make sure there was no oil or factory debris in the barrel.............after that heck I just sighted it in!!!! Never had a problem. It was mostly the brand of ammo or load that made the good groups not barrel break in!

Barrel break in came from barrel makers that didn't want to back up there claims and companies that made cleaning patches and bore cleaners!!!!!

I never heard any ammo maker say a barrel needed to be broken in!
