I did not try any 180's. All I used were cheap factory 150's which I don't even remember what brand they were. I was not really going for groups. I was just trying to break in the barrel at the time. I followed the break in process recommended by McGowen. Fire ten shots cleaning between each shot then clean between each 5 shot group for another 40 rounds.
