all my wolves are SR but they are very consistent primers, in a side to side they out shot the federal's i have pretty handily.
my only complaint about them is they won't run through my primer tube filler machines and i have to pick and poke the tubes full by hand..
airc i only paid like a hundred bucks a sleeve delivered for them.
i miss the 'cheap' magtech primers too, i have a couple of large rifle hunting loads for them that are very good.
