I have seen that ammo cause problems in classes. I would suggest you ensure you have an in-spec 5.56 chamber and a new extractor spring installed to mitigate problems.

Seems like fairly consistent ammo, but a tad slow for a supposedly M193 spec round. I've seen this stuff at <$9.00, perhaps it is not a bad buy.

Where have you seen it that cheap?
