Have been resizing some 223 brass using my Lee dies. At some point I ran into a stuck case and didn't want to deal with it right away.
No big deal I have a brand new set of RCBS group AR 223 dies on the shelf, part # 11107. Got thru all my cases that I wanted to do. Started sorting out the cases that were going to need trimming. Went to put one in my RCBS trimmer and found the case wouldn't slip over the alignment pilot. Tried a few more and found that none of the cases I resized with the RCBS dies would slip over the pin.
All cases passed a case gauge test.
Upon checking the ID's and OD's of cases found that:
Lee cases ID=.218" OD=.244"
RCBS cases ID=.215" OD=.241"
Note: alignment pilot is .218" on the case trimmer, also wouldn't fit on a Lee trimmer.
Resized all the RCBS cases with a Hornady 223 resizing die and got the same numbers as the Lee dies.
Anyone have thoughts on this?
Is this normal for the "Group AR" dies compared to their "Group A" dies?
