Today I made up a batch of 8x60r Krop using .348 Winchester cases. Started off with a RCBS forming die and a set of 8x60r CH4D dies. The forming die would not push the should back far enough so I had to use a Lee 8x50r as an intermediate die. The face of the rim was chamfered off on a small hobby lathe. A Lee 205g 330 mould was used to cast projectiles that were sized to .327. I need to ream out the neck so that .330 projectiles can be used. I started to ream out the neck by hand using variable reamer set to 8.3mm but this will take for ever to do. Any ideas on a faster way of reaming out the neck?
