I have resized 6.8mm brass to 6.5mm using a .285 bushing. : .264 + .012 + .012 = .288 : if, .003 neck tension then .285 is right
I then took the 6.5mm brass to 6mm with a .267 bushing. : .243 +.012 + .012 = .267 : calc to zero neck tension so .012 neck must be wrong, maybe after squeezing down.
I have loaded and shot both these 6.5mm and 6mm wildcats with sufficient neck tension that I could not pull the bullets with my fingers.
I was using Starline brass.
That is all.
