While I see these as a gimmick, IF IF IF they were reliable and reasonably balanced, and well regulated, such a rifle in a .400 calibre might be very useful. in a .450 or .500 deadly but very heavy.

Maybe a .416 Rigby, or a .404 Jeffery would be better.

Would be great if accurate enough for plains game shooting as well as big dangerous game hunting.

If I was a uber millionaire. I might consider one. Just for the sake of it.

Not sure of the Blaser platform though.
