Muzzle cap problem

I have a new Talon SS. It’s about three months old with about 3,000 rounds through it. Up until a few days ago it’s been a tack driver. Recently about every 5th or 6th shot is a flyer. Opening up about 1/2″ at 10 yards. While wiping the gun down today I noticed that the muzzle cap was showing signs of pellet strike damage ( I’ve attached a photo). The gun hasn’t been dropped or banged. When the flyers started I did clean the barrel going from breech to muzzle.

I haven’t had the barrel out or the muzzle cap off. I’ve also noticed that the Sound Loc baffles have started to rattle a little bit inside the shroud.

Has anyone else had a similar problem? I’m open to any suggestions.
