Joe,I never had that problem with RWS brass, I use it in 7x57R,6.5x57R,9.3x74R,9.3x62,9.3x72R,8x57IRS,8x57I,and 5.6x50R.
I agree it is a little softer than old DWM, but I found that an advantage. Maybe you just had a bad batch.

6.5x57 dies are used with either version,just different shellholders.Actually,you can use 6.5x55 dies( if you already have them)as necksizing dies, if you only have one rifle.
