When you put it together did you bed it in the stock ? Is the bolt rubbing on any thing as it is being moved forward ? Have you tried to feed with less rounds in your magazine . have you looked at the bolt face to see if the brass is being held in the proper position to feed correctly ? There are at least a truck load of possible things to look at .
I went back to fresh and put the gun together from scratch again. I ended up shimming the magazine catch with a copper brake washer ground to fit to make the rounds hit the feed ramp. It works pretty decent now with an unmolested magazine.
