We discussed this awhile back. Their 0 to 415 yard claim is quite literally a stretch.
Actually, it's a claim any cartridge on the planet could make, since they make no reference to maximum height above LoS.
As it is, I did the math and you'd have to be willing to be sighted 5" high at 210 yards, zeroed at 350 and be 5" low at 415 yards. That matches their claim exactly.
I don't know too many folks willing to be sighted 5" high.
Plus, as I said in the other thread, basing a new cartridge off a long action seems to be bucking the current market trends and consumer interest.
Oh, and I think the rifle is $1,600? No thanks.
