Smart Parts All American
I have "normal"...that's .689 isn't it....
/me goes and checks...hmmm..I thought the bore size was stamped on it, but it wasn't...
I've shot age old Diablo Blaze through it...was good.
Old RPS Euro-flite too...didn't break significantly more than in the Hellfire barrel...
Newish Midnight...fine...
Old Midnight...OK too...but old Midnight seems to break more than old Blaze.
(Can you tell that paint is a bit of a problem in Iceland *grin* small market...bigger imports = more economical...i.e. paint gets old....)
I feel that the paint needs to be a little better for the All American than for the Hellfire...but that may be because added length means more chances for the paint to rub the wrong way against the barrel and break...
Also I find I need to turn the velocity adjuster more up on the AA vs. the Hellfire, probably resulting in a harder blast against the paint, so that again increases the chances of a break...but 12 inches instead of 14 may decrease that.
I don't think there will be a significant difference in accuracy in a 14 inch one vs. a 12 inch one...but gas consumption and breaks might be better in a shorter barrel......
my best
