TargetTalk

I apologise as it's wayb outside the normal TargetTalk gambit, but given the knowledge on this board...

Can anybody give me the dimensions of the X-ring on the B-27 target? The NRA and Canadian PPC rules do not help, only saying "with an X ring added for tie breaking"?

I found this on another forum.
The X-ring is actually an oval.
The B-27 target is used for LE competition and Concealed Carry qualification.
Use these dimensions with caution - totally unofficial.

Ring Width Height
X 55 78
10 100 150
9 200 300
8 300 450
7 400 600
