The .460 is about the only factory round producing that amount of fpe, so older black powder rounds are OK as well as all of the nitro-express SxS rounds.
The .600 NE comes close.

Seems to me IIRC, it runs 1910fps with a 900gr. bullet, so 7,293fpe, under the 7,375fps limit.
Oh, just remembered the new one. I guess the .700NE would be over at 2,000fps with 1,000gr. bullet @ 8,884fpe
Stupid laws.
