[QUOTE="Mikecr, post: 1826094, member: 1521"] When you pull cases smoking from the chamber they should have less than 1thou TIR Your ammo is up to 6thou TIR. That's very high, and you see that the cause of it is not expansion method. When you get your loaded ammo down to actual 2thou TIR, then you may see expansion method reduce it to <1thou -if that runout is born in the necks (instead of body). But with turned necks, your runout is likely coming from sizing of case bodies. Out of curiosity, have you measured thickness variance with these? [/QUOTE]
