I shoot approximately the same powder charge out of my Whites. And with a heavy conical, accuracy is exceptional. Also I discovered for those worried about penetration.. 65 grains of Triple Seven 2f and a 460 grain conical will penetrate 8 inches of solid poplar fire wood. They mushroom to almost an inch, and retain almost all their mass. What more could I ask of a bullet and think of the devastation to a game animal.
