Hi everyone, I know this has been asked a lot, however after 20 hours of searching the internet I have still not found a definitive answer. Is there a mold that drops a 130 to 150 grain boolit that will feed in every 300 blackout AR upper. Early this morning I settled on the NOE 310-135, after more reading I am having second thought's. I have read a lot of stories about people spending several hundred dollars before they find a mold that will feed reliably. TIA.
