Force must have been the awnser to get them going from memory!

Greetings again,
This shell holder mis match has fascinated me, probably the previously mentioned OCD, so I have done some measurements. The rim recess on the Redding no 1 shell holder was about 12.25mm as near as I could measure which is larger than any of my 6.5 x 55 cases (Norma, Lapua and Winchester) at 12.0 to 12.1mm. The lip that fits into the extractor groove measures 10.3mm but all three cases measure 10.4mm so this is why they don't fit. I checked the RCBS no 3 shell holder, equivalent to the Redding No 1, with dimensions of dimensions of 11.9 and 10.3mm so the rim wouldn't fit in this one either. @andyanimal31 I would be interested to know what the extractor groove on your cases measure as well as the inside dia of your shell holder lip. I suspect that the latter dimension may have changed.
