Well done mate getting a range report done in swift order!
Now there is verified evidence that these loads are achievable in 2 rifles, so if anyone else in the world is now looking for data then they have a goal to work to thanks to you mate!
Glad to see you got your little 'surprise' packet going so well, it really is a powerful round be told, more than capable of taking dangerous game if loaded with proper projectiles matched to the task!
