Here is what the article said:
So, being a bit of a 6.5mm fan, I got excited when Nosler gave a sneak preview of the .26 Nosler
. It was supposed to push a 140-grain bullet at 3,375 fps, a quantum leap over the .264, except that they were wrong about the velocity. In the 26-inch barrel of the Nosler Model 48
I used, actual average velocity was 3,425 fps — a bonus of 50 fps.
