RE: RETUMBO powder
Hodgdon says you can squeeze 60grs into an 06 case, but it will be a compressed load. estimated velocity 3050fps.
One more question if you don't mind. We talk about muzzle velocity and downrange velocity all the time, but I never hear anything about the acceleration rate of the bullet down the barrel. The acceleration rate must have at least as much to do with putting rotation on the bullet as muzzle velocity, so why can't I find any info?
