I got a Number2 shell holder (little smaller) and it doesn't rock any. Also seems to fit the 08's little better. Somebody on another page recommended that. Will let you guys know how it goes. Been out shooting in Ky for the past 4 days. Sorry havn't responded back. The shell holder is new and only been used some. So well see if that works. I used the Lee shell holder before with my 308's.

Mossy, i am using that machinistshim setI showed you from work, that are supposed to be accurate within .0001".
