Went shooting today with some USAammo 168 and 175 it shot ok, but when shooting the 18th round out of the box of 175 it blew the primer. I was shooting a R700 Varmint 308. Never had this happen not sure what to do about it. I read another post where this happened with some BH ammo in a few gassers. They called BH and told them about it. Should I do the same and call USAammo and let them know or try another box out?
