Pongo12,
That rifle sounds like a nice build, US869 is good powder in the 7mmRUM that was Stugs I am getting 3250 @ 25degrees with the 180s but get velocity changes of about 100fps when the temp go down to 10degrees so come winter/first frosts it may be worth checking that out, just a thought(good excuse for more shooting).
The 180 VLDs that you are using are they the hunting ones? And what distance are you getting those bang flop results to?
Anyway good luck and enjoy.
