The 450MHz figure feels about right. Perfect connectors are OK to handle
a bit more, but you're living on the edge.
>No ratings are given for BNC,
Since the inner contacts are about the same as N, the rating would be
about the same too - but limited in practice by the small size of cable
that a BNC will take.

As a low-frequency limit for BNC-type inner contacts, the MHV and SHV
series are both rated at 10A DC. Again, that feels about right.
