Depends on your chamber but have made plenty of 6.5x55 cases and 8x57 cases out of 30/06 cases and in military rifles they never needed neck turning. 8x57 cases were resized and cut off with RCBS trim die and loaded with no other prep. I have heaps of 260s and also 243s made from 308 cases and they work well.
