Tikka 6 creed PVA 108eldm feeding issue

[Bc45]

Looking for some help here. I have a tikka t3 with a PVA osprey prefit. I have 45 rounds through it and it cycled and shot flawlessly. Took it out of my rokstock to have some changes done to the stock and thrown it in a krg. It cycled pretty badly where if I went slowish it would get stuck pushing the bolt down and lifting it up. It was “better” when I cycled it fast but not perfect like before. Put it in a stockys VG and same thing. Tried another tikka bolt and same thing. Took trigger off and fed it and same thing. Tried different lots of ammo and same thing. Only thing is I don’t have any other ammo besides 108 so can’t try that. Last resort I went to clean it and still same thing. Any advice could it be the throat in the pva?

Heres a video of me feeding it with different rounds and speed. I know it works going quick but it wasn’t like that before so just wondering why.

It sounds like you pushed some type of debris into the lug area or your chamber. Coloring a loaded case with a sharpy might help you identify the tight spot, or look around with a cheap borescope
