Axis xp2 223 light strikesirs

[Bigguns]

I put my new axis Xp heavy barrel thru a 50rnd break in, I did have 2 out of the 50 hit the primer and not go off, I reloaded one and it did it again.
I'm shooting the federal 55gr brass case in the redish maroon 100rnd box.
ill try a more typical round for a bolt action I was thinking of using the Winchester 64 grain xp hog season bullet?

It was the ammo......PMC bronze and low end Federal worked fine......the 223 military grade had harder primers....so I sold the rounds.
thanks all!
