I have gotten6 or7 but they have all occurred while I was shooting arrows other than my ACC's. I have only gotten 1 with ACC's but I have torn up a bunch of nocks and a bunch of bushings. I have shot ACC's at least 80% of the time since 92 or 93 (can't really remember which year I started shooting them) but it seems like it's a lot harder to Robin Hood an ACC because of the bushing.
