You must like to eat gas? If not, you better find a taste for it... You might make eat so much gas with this one that your eyes water!
LOL, I had a little fun with this one.
On a serious note, My 10.5" 223 is pretty gasy and will burn your eyes. My 7mm mag with a 24" barrel (that I'm pushing hard) has unburnt gas that is detectable.
Best of luck!

Not bad at all if you use the right brake. See my post above on barrel length recommendations for Ishak.
