6.5x55 case rim is slightly larger, often requires a special shell holder instead of the usual RCBS #3.

Yes & No. I had to get a #2 shell holder for my Swede BUT others reported they use #3.
I'm 'guessing' here, it may be in the brand of brass. If you run across any 6mm Remington brass, pick it up. A pass through a sizing die and it is good to go.

I have a 6mm R & 6.5X55 and the cases look SO similar. I haven't measured the exact diff
but they ARE very close.

that has been my experience.
brass from europe is "correct" and takes the larger shell-holder
brass from the US (including PMC) is just like 308-30-06-45acp brass and takes the 308 shell holder
I assume all dies and chambers are correct and the US brass is "fire-formed" the first time it is fired in the chamber, not the shoulder, but the body forward of the web.
