I finally fired the last 10 of 100 last week with the suppressor and it averaged 2680 at 39gr. Unfortunately a couple of the shots had a little bit of bolt lift, so that may be all I can get out of it for powder, maybe it will speed up after another 100.
But also worth noting my chamber is throated for 131 black jacks, so the 133EH is seated pretty deep in the case and sitting .010" off the lands. Throating it out optimal for the Berger might allow for some more juice, but if I were to know what I do now and restart, I would go with 25-284. Which this chamber may get punched out to after I toast my lot of brass, if there's enough meat on the shank to allow it.
