Those two shells have been on many adventures with me - they're my two hunting buddies!
Don't want to pop them-off.
Samuel, I did have a bit of lint from my polishing cloth stuck in one of my barrels.
Went to my toolbox, got out a tweezer(the only thing in there other than a spool of dental floss - for my toof) and extracted the said lint like the pro I am.
A job well done - no doubt!
