I got a T-7 press a year ago but have not set it up yet..I have been using a RCBS press for 20 years ...Anyway the runout thread got me thinking, are turret type presses pron for creating runout?
The premise that a press can help or hurt concentricity is greatly over rated, IMHO. All a press can do is push cases into and pull them out of dies; ammo is made in the dies. And no dies can make straight ammo if the case necks aren't true.
