The brass ball in the nose cavity is an interesting twist:

Yeah, I saw that. I can't wait for Ian to cover it on Forgotten Weapons in 30 years.

Hey, man, give 'em a break! Their marketing team is just trying to spin things to make you believe that BB has a purpose other than keeping lead out of the tip!
(Maybe the should have asked the Russkies how they did it with the 7N6 round a half century ago...)

Or the British, 110 years ago, .303 Mk VII.
Sad thing is, someone out there will actually buy it. I hope I meet one of those people in person. I think I’d have a few questions for them.
I'm sure they know a lot more about ballistics than I do, but I thought bullet instability was caused by having the center of mass behind the center of pressure (or drag). That's the whole reason the bullet has to be spinning to be stabilized. If that is true, then I don't see how moving the center of mass rearward would help. Also, as others have pointed out, a brass BB in the tip actually moves the center of mass forward as compared to an empty hollow point.

Looks like the 350 grain bullet out of the thicker walled .338 Lapua case will really deliver the goods very far out ! Now for an improved K31 straight pull precision rifle to fire it !

Pretty much. Without gyroscopic stabilization, the heaviest part tries to lead. That's why BBs & musket balls are round, and shotgun slugs meant for smooth bore barrels are extremely stubby with (usually) a concave base to offest the smaller diameter tip.
