Maybe polish the ramp up. Sometimes a barb will do it.
I have thought about that, last time I cleaned it up I noticed the finish of the feed throat is starting to flake off, so maybe next couple pay checks will have to order a new feed throat and polish kit that mcarbo has and polish the feed throat ramp up. I honestly don't think who ever had this gun last really cared for it enough to take care of it, looks like they just loaded it up and shot the snot out of it. Me things like this I like to take care of it.
