Sig 716i Tread Problems

I recently purchased the above mentioned firearm and went to sight in today. Prior to shooting, I noticed the bolt would hang up after I full charge on the charging handle and full release. After using the failure button (i.e. forward assist button) I got the bolt to go into battery and proceeded to fire with no problems. After sighting in (which was never achieved due to function problems) and checking casings, I noticed I was having very light primer strikes and was worried about the bolt not going into full battery when firing and decided to pull the bolt out and found that the bolt would not release and twist to engage and disengage the rotating mechanism.

I am worried the bolt is damaged and will contact Sig about this problem. But didn't know if this was happening to anyone else. I was shooting regular Winchester white box M80 ball for shits and giggs to sight in and will use my federal gold match ammo to precisely sight in.

I also noticed there is a ton of brass shavings on the ejector and bolt face and around the chamber of the firearm. If anyone can help and see if this is a common issue that'd be great.
