Kenny Jarrett used them out of a .280ai at 3200 out past 500.
Used my Jarrett 280 for legal culling of does, plus normal hunting applications for about 28 years. 99% of the deer I've shot with this rifle have been shot with your load. I've killed from point blank (under my stand), out to 600+ with zero problems. Won't quote the actual number of kills for this rifle/load, but it is substantial.
