I never got around to loading any but somewhere I have a box of Nosler E tip 150 grainers.
I am a great believer in 180 grain bullets for the 30/06 but there are times I like the idea of
being able to kill deer on the spot. A 150 grainer at 2900 striking velocity is more likely to do
that than...
I have fire formed many 220 Russian to 6 PPC. It works best if you establish headspace with the bullet at least engraved a bit.
Just because a case appears to fire form well does not mean that it does.
I very much agree that too much data is generally about right. Data, in and of itself, tells us nothing but lack of data may lead us to incorrect conclusions.
As a former short range Benchrest shooter I now freely admit to cleaning my barrels far too often. That idea came from the data from you...
I see this all the time in the archery world. People want to change to something more in tune with their needs but then also want to control the narrative.
