Japan's heavy machine-gun round is noted solely as "13.2mm" and does not list a case length.
Maybe add the 20x124mm since Japan now uses it to shoot at enemy soldiers because it is no longer an effective AT round? :D
One minor nit is that I think that the 6.5x55 Swedish Mauser will probably have a different name. :)

That's because I never bothered to look any further than navweaps for this one which IIRC does not list the case length. Looking around, OTL it is based on the French Hotchkiss so it is probably best to assume that Wesworld Japan's 13.2mm is a 13.2x96mm one (KISS).
