Badger barrels included a break-in procedure with my brother's AR10-T when he bought it.It is a progressive shoot and clean routine.
I was a plastic injection moldmaker.You would be amazed at the damage that is done to 4140 mold plate steel just as hard as barrel steel by plastic flakes or plastic nozzle drool if a mold closes up on it.The plastic dents the steel.
So the issue is metal fouling.The new barrel is a little furry inside.The fur rubs off some jacket metal.Do you want the next shot to run over that metal fouling,which has a volume that cannot be compressed?The break-in process is about removing the metal fouling while wearing the fur off so it does not get battered into the steel.
Just as an aside,if it is a blued steel barrel,the bore got etched by the bluing process,which is pretty furry.Takes a while to shoot that off.
Thats my story and I'm sticking to it! HiBC
