Well I'm using virtually the same as you component wise....imi brass, cci primers, n133

SBK = 24.5gn n133 and good for sub 1/2" MOA

53gn V Max = 25.5gn n133 good for sub 1/2" MOA (should be same for A Max)

all from a remmy 700 SPS tactical 1 in 9

hope that gives some help....please build up to these charges as they are quite near pressure threshold in my rifle...im also seating my bullets quite long (2.290") to be close to lands ...
