Crowning Damaged. No effect?

1999 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.

From what I've read and what I've been told, crowning has to do with causing turbulent airflow to become more stable when the BB exits the barrel. More stable airflow= more stable BB= more accurate shots.

That's why I would have assumed the burrs on my crown would have affected my shots, but the accuracy is the same as ever.
