Rosecrans1: SD=8.92 average velocity = 2743 in my 22 inch Rap, 30.0 of 8208, measured 29 feet from the muzzle.
The Nosler site has the Varm max charge for 8208 at 31.0 for velocity of 2953 out of a 24 inch barrel and this was the top velocity of the powders they have listed for the 90 Varm.

There is about a 100 fps gain from 30.0 to 31.0 in the Nosler data, so in my Rap it should max out at about 2850
