Looks like the 50 WSSM variant(whatever they ultimately call it either .50HP or 50 OSSM or something), should outperform all three of those big bore options.
I gathered roughly the same from watching the show. Velocity is probably pretty slow and I wouldn't trust it's accuracy when the distance gets stretched.
