I was planning on trying that with some factory rounds but haven't bought any just yet. As far as a wet chamber no it's not....Looked at this thread again and I keep coming back to headspace. There is no way you should have copper at the start of the lands like you have in the video, and the firecracking at the breach seems a bit excessive for 130 rounds. How is it to close the bolt - getting resistance as it is chambered?
You may want to go buy a box of factory ammo and see if they leave marks like that just by chambering and removing the rounds, and/or take it back to the smith and have him double check with a Go gauge. Also measure the OAL before and after they are chambered for both your loads and the factory rounds. Another thing is I hope you are not shooting that with oil/solvent in the chamber - guessing not, but a wet chamber creates excessive pressure.
