I've seen 112g for the RUM and 126g for the Firebird...I know it depends on who/how/what did the measuring tho. gun)
And the AM is right about 120g, best I can see anyway.
Yes, that's normally the case.
I have not seen the Firebird that high but have seen the Warbird from 120 to 127.2 (just rounded it whole and measurement was done by John Lazzeroni himself).
Not sure of the 7MM AM's capacity but Kirby is only 20 minutes away from me if I go that route.
