Crowning Damaged. No effect?

2000 Views 5 Replies 5 Participants Last post by  woogie
One of my barrels has two large burrs on it's crown, but they're not in the way of a BB's flight path. They do however collect cotton when I swab a cotton swab tip on the crowning indicating a non-smooth crowning. I honestly haven't noticed a difference in performance. Can someone elaborate on why this may be?

This barrel's crown is no where near perfect, but it's still shooting like a champ. So I'm beginning to doubt the importance of a perfect crowning.

The crowning is not 100% essential to the flight of the bb, cut a nice crown will definitely help a lot.
