I used to use AA Fields until 2013 when they started to get grubby. For me in the Walther, they used to require only 1 mildot for 45 yards as opposed to 1.25 or so (25yd zero). This changed when they started to get grubby and I got fed up with paying the extra.
The few tins I have left are die 29, 6.9.2011, 4.52, S1 00 and die 14, 24.02.2012, 4.52, S0 00.
It's the Indian not the Arrow
