They had the aluminum tipped 162 gn 7mm. So they have experince with al tipped bullets. But I like that these seem to go beyond that. They're concerned about bullet to bullet variability and getting the most consistent bullets possible to shooters. Of course nothing is more consistent than lathe turned monometals. But those have issues with tips and hollow points that may reduce BC or terminal performance. I'd think the A-tip will expand on game at long range. Better at least than a tipped copper bullet. The A-tip jackets look pretty thin.Wasn’t there an Aluminum tip 338 by Hornady many years ago but was ahead of it’s time I guess before Long Range shooting really took off.
