I don't use the expander ball when I resize and only use the specific bushing (depending on the Brass being used). I've been using the SAC seating die for about a month now and they are spot on. Been able to use the same seating die for the ARC, Grendel, Creedmoor, .308 Winchester and even for the .223.
are you using a ballistic calculator (Strelock Pro). I believe it might have the G7 information in it.
I tried them at 2.250 and 2.260 and my groups were bad. I've got them down to .5 MOA loading them out to 2.287.
