They are towards the upper end but not near any pressure limits (mine anyway). I'm cheap enough that I like to get at least 10 reloads out of a case. The 300SMK and 869 is the load of choice as the ES are less than 5 fps on the groups I've chrono'd. Also it only lags behind the Edge a little, which kept me from rebarreling to an Edge.
I may be the slowest guy on the mountain . . . . but . . . . I'm on the mountain!
