Obviously mixed results, which is good for some, bad for others
I've ran about 2000 rounds of Fed Bulk thru mine which works well (few mag snags). I then decided to try a box of Win 333's and had, probably, 15 or so Fail to Ejects. So, me in particular, probably won't try them again.
Definitely try them, find one that works best, and stick with it until you find something else to try
