[QUOTE="ken snyder, post: 621957, member: 26019"] Those velocities are up there no question about it. The 30-378 is good for 3200+ with a 26 inch barrel and a 200 grain bullet. the 338-378 in 250 grain about 3200 with a 26 inch barrel. start adding barrel length and the velocity differences start vanishing in a hurry and that is in a factory out of the box chamber dimensions. I think that he may have access to some of the super magnum powders such as reloader 33 that have not hit the shelves for the general public yet and that alone is worth 150 fps ( according to information released at the shot show) I don't believe that any exta ordinary velocities can actually be assigned to the 500 Jeffery in those bullet weights, diameters and might only be significant in the heavier weight bullets in the 338. Apples and Apples, Oranges and Oranges, pressure for pressure and barrel length for barrel length. Even bullet coatings, but see it as a good wild cat in larger diameter bullets because it already is. [/QUOTE]
