People are getting real nervous about 300 BO since the rounds will chamber in, and blow up .223/5.56 guns. I am seeing those at least once a week. Yeah, stupidity, but there is still a legal risk that some manufacturers are not willing to take, especially ones that are selling everything they make faster than they can make it.
I don't know if that applies to KT one way or the other, but it does apply to some others.[/quote.
I mark my 300BLK mags with tape on them in big letters and numbers.
I haven't heard of anyone getting sued for people loading the wrong ammo.
The manufacturer isn't liable for that.
There would be someone trying to blame the AR-15 but it would go nowhere.
