Jeez. The water bottle looked like the real deal, but some of you have shot trucks (and possibly porta potties) with stuff a lot more powerful than the Lapua round.
I have seen vehicles shot to bits with 20mm Vulcans that didn't blow up like that. (On firing ranges in the US) The potty and the truck obviously had explosives inside.
Not to downgrade the round, it's likely an heir apparent in the sniper world, but unless it's got a core of red mercury, it won't do what the video shows by itself. CB
