I know a few years ago there were reports of kabooms with Frontier ammunition. Upon review, it looks like most, if not all, was 5.56 out of AR platforms. Anyone shooting the subject ammo out of bolt guns and/or heard of any recent vintage issues with these particular loads in .223? Interested because my bolt guns love them but if they`re not safe..... Thanks in advance for any input.
