The 140 7mm AB has been consistently accurate for me in a couple of 7RM's,and the 7mm Dakota at 3375 fps.Ditto also the 150 gr AB in the 30/06.
I have tried the 130 AB in a couple of 270's and they did not want to shoot.
The 7mm 150 SS(both the old and new)have also been very accurate in 7RM and 7mm Dakota.Driven at 3150-3225 from these cartridges, I notice it shoots a full MOA "flatter" to 500 yards than more conventional bullets....I don't know why....
I can't get the 130 SS I or II to shoot in any 270 Win I have tried.
Have not shot anything other than coyotes with the SS,but was surprised that the give nickel-sized exits on these little animals,even under 100 yards,and do not blow them apart which surprised me.....I am more used to seeing coyotes blown up pretty badly from 270's and 130 Partitions.The SS II seemed pretty tough to me.
I have a feeling the 130 270,both AB and SS II,because of their length,might need a faster twist that 1-10 found in most 270's.Just a guess,because I do not have a 9 twist 270,but I can't get either bullet to shoot.
