It would be easier if you went round the segments clockwise or anti-clockwise
Hey - it works !!

Just got 80 with the HW75 open sights. Missed the 11th red by a gnats.

Bet when we come to do the comp for real I make a real pigs ear of it.

Very hard to see the sights against the background of the black segments tho - as has been said before.
