Intersting info regarding pierced/blown Murom primers with .223/5.56 Loads
I'm a maggot in another life you know
Interesting..... I've used up to 24.5 grns of wildbore with a KVB223 and never had this issue. Pancake flat yes no leaking of piercing tho.
Quite a few have Danny. When I started Myles sold me the copper coloured ones under a different flag, but apparently the KVB223s also started this way which is why I got 2000 of the things. My bolt face is now nicely pitted with either blow outs on the angle of the primer or the pin.
Either way they aint going near my AR again...ever....not even boxed.....no chance.....
It shooting well at the mo as well, although I have dropped to 24grains.

It's my understanding that the KVB223 is for bolt guns, and the KVB556 version is designed for ARs and military type rifles (something to do with floating firing pins IIRC) and that has a thicker cup and more primer brisance. There's also a KVB223M which is a mixture of the same brisance as the standard KVB223 and the thicker cup of the 556.
