Might just be the valve poppet has not seated properly yet.
Did you add oil to the valve before you put the 12gram in, like the directions say?
I went and flooded the sucker, and ended up having the opposite problem. I popped in a 12gram, and did not hear anything. no hiss at all. Popped it into the SA8, and still no hiss whatsoever.
I was 95% sure that the 12gram never pierced and I was close to doing something stupid.....
