Thread: 6.5x47 with a Lee Collet Die

I'm having real trouble with concentricity using a Redding type-S bushing die on once-fired cases and am now looking at other options for neck sizing with low runout. Can a 6.5x55 or 260Rem Lee collet die be used for the 6.5x47 please? Will I need to take to it with a grinder or turn it down in length? Will it matter that the die is not shaped internally for the case - I'm thinking that the more gradual shoulders on both of the above might restrict the amount of neck that gets sized on the 6.5x47 case with the 30 degree shoulder. Could I run a reamer into it to fix this as I gather that the dies are not hardened? Any advice much appreciated!
