While seating the second round in my encore, I noticed that it lacked about an inch going all the way down. I removed the breech plug and drove the bullet back out of the barrel. After inspecting the bore, I noticed that there appeared to be melted plastic where the bullet hung up. Was this melted sabot from the first shot, or was it from the second sabot and caused by loading it into a still warm barrel?
I want to try seasoning the barrel, but I'm not quite sure how. I was told to apply Borebutter between shots, but do I clean between applying the Borebutter?

Thanks,
