I used the Redding shoulder bump die and the Lee collet die to neck size. I bump the shoulder a few thou everytime so I have consistant brass. Winchester brass has gone to shit lately in the 25-06 offering, very soft and stretches around case head. I just ordered some 30-06 Lapua brass to neck down and play with. I have found the 270 WIN brass is a bit tougher and you can trim the longer 270 neck to your desired length.
