Looks to me like the fired round are extracting but not ejecting. You said this is a new firearm so my first question is did you clean it before taking it to the range. Grease in the chamber could cause slow/short extraction or something causing resistance with the extractor. After a good cleaning I'd try a different ammo. One of the few new firearms I purchased was a Ruger Mk1 that gave similar problems. After a few GOOD cleanings and a few hundred rounds through it the jamming went away.
