Seen a lot of stupid stuff in the years and a lot has been blamed on barrels regardless of the maker! Some of the things that we've seen and continue to see......
Damage to muzzle crowns. Weather from cleaning or from when the barrel was initially installed! Just repaired a .30-06 tactical rifle. The gunsmith who installed it damaged the last 1/2" of rifling. The customer had some bullets going thru the target sideways at a 100 yards. He sent the rifle to us for us to look at. That's what we found. We cut off the 1/2" of the barrel. Rethreaded the muzzle and recrowned it. The rifle is not shooting 1/3moa or less with box ammo.
Not enough bolt clearance to the breech face of the barrel. Last barrel we had went from shooting mid .2xx's to now shooting mid .1xx's.
Barrels not tight enough on the actions!
Damage from cleaning!
Bullets vary from lot to lot!
The list can go on!
