When it fails, it will likely leave that thinner walled ring of brass in your chamber. Fine as factory loaded ammo but terrible brass for reloaders! Brass like this and other garbage, cheese grade brass like AMERC are the reason I cull all of my brass which I do while running it through my Harvey Deprimer.īesides the danger of an overpressure situation which is bad enough, this brass has another dangerous flaw! That sharp transition step from thick to thin is a severe stress riser and has confirmed cases of case separation and I have seen it happen with my own 2 eyes!
