old military 6.5x55 swedish mauser or new custom build

[LRRPF52]

As long as the 6.5x55 case fits inside the seating body without binding, and there is enough travel to seat long projectiles for it, it might work. I looked at my .260 Rem Forster micrometer seating die, and it will seat Grendel, but the Grendel has a smaller case diameter, so I'm not sure if it works vice versa, I tried a .260 Rem in the Grendel seating die, but it's a different make. My concern would be that the die might not align the case properly, and you get run-out.

You will need a different shell holder though, as the Swede has a .480" case head diameter. If you already load for one of these, you have a 6.5x55 shell holder:
