Like said any marks on the bullet? I suspect your loads are a little long and contacting the lands with the bullet or not sizing enough or both.
Gendel compound throat is there for start pressure reduction mostly from what I understand, works IMO. Gets the engraving of the rifling started on the bullet more gradually instead of all at once.
Edit to add cover a round (dummy Round) with a sharpie and chamber it makes contact where the sharpie mark rubs off might give better indication than marks on bullet or brass.
