FYI Viht data has changed year on year for no other reason that they can

It is safe to also assume that powder data produced 10 years ago for batches of powder produced 10 years ago may not be EXACTLY the same as powder produced this year

its the reason people who are wringing every last bit of accuracy out of target rifles try to work with large volumes of powder from the same lot number

have you tried magnum primers?
I am about to switch and run some N133 60gr loads on magnums as a test
