Well, I think you are concluding you could have some soft brass. Realize I do not want to lead you into a dangerous situation. So please be careful as I am not there to see the results in person nor should I make this call for you from a distance. But 3 to 4 thousands is not a "muffin topped" primer to me, especially if it has rounded corners. I have seen them from max loads that when rolled on the bench top turned a tight circle. I called those an over pressure load. I think all you need is a cool chamber and some lower fall temps with this brass. Go to 3 shot groups at 200 yards to check this load. If you notice a 3rd shot having a heavier bolt lift I would back off to 2 shot groups and do more of them at longer distances.
