[QUOTE="MagnumManiac, post: 844917, member: 10755"] That is what I'm saying, I use .0015" under bullet diameter across the board, it's ample for all of my rifles, except my 375Weatherby where I run .002" under bullet diameter, just for piece of mind. I think people misunderstand where the powder burns in general, most large cases have significant amounts burning in the throat, no matter the shape of the shoulder or the length of the neck, in smaller cases I believe this notion to be true, especially in the 222 based cases where the flamefront stays in the case and Ackley based cases. It may be true in the WSM's, but slow powders don't propogate the flame through them easily which in most cases would cause a plug of unburned powder to be travelling into the throat behind the bullet. I may be wrong about this, but I've never seen it testing a few WSM cartridges on my Pressure Trace equipment, peak pressure appears to occur around the same point in either 300WinMag or 300WSM.
