I'd like to read this article to see what exactly what were his definitions and testing parameters. Certainly I can't make statements about a given load shooting well in all rifles, or a "pet" load being the very best shooting load for a particular rifle. I will say that there are loads out there quite likely to shoot very well, well enough often enough to be useful as shakedown cruise test loads for new rifles.
I tried to find the magazine, but I think it was a victim of a toilet backup/overflow a couple of years ago. Pretty sure it was in a Shooting Times from the early-2000s.
