I certainly own firearms I don't need...I get it, but this caliber...I mean if I saw any utility, I would get it.
There have been several wildcat choices in this category for years...either the 6.71 Lazzeroni Blackbird or the 6.5 Ultra Mag. An ultra-velocity 6.5mm just doesn't perform that well on game.
Nothing personal...ultra-velocity 7mm cartridges have the same reputation. The 7mm Remington Mag and 7mm Weatherby Mag are both about right velocity-wise.
Truth is...the .264 Win Mag really represents the practical limit on 6.5mm cartridges. Maybe a little bit of a stretch based on it's popularity since introduction.
