Bullet casing change

[727Sky]

I would think that the residue in the firing chamber or even the barrel would clog things up, like the gas return tube or even the firing pin.
JMHO

Always a problem I agree.. I do not know why this would be a dirtier round than what is being used presently though... When I first saw the round I was thinking feed problems but they fixed that by a different method of chambering.. Anyway interesting .... I also liked the idea of a heavier round than the 5.56 but still having the weight savings due to the lighter casing..

So your alive and kicking? 

Good..

All stories of my demise are propaganda and fake news... Unless I really am computer generated and do not know it ???
