[QUOTE="varmintH8R, post: 922418, member: 39801"] I promise I am not trying to be confrontational:D. I am very interested in the result of your testing (and if we ever see bare ground here again, hopefully I can contribute). By design, a throwers set volume is just that - volume. Weight is a function of the thrower's chamber volume, and if weights happen to be similar it merely represents a consistent bulk density of the given powder. I agree that measuring relative to actual case volume would introduce another variable that could be meaningful. With no data to back me up (prove me wrong!) my first thought is that the resolution of a rod measurement would be too course to measure the relatively minute volume changes between cases fired in the same chamber. This would be especially true of extruded powders, where granule orientation will effect bulk density significantly. I'm interested to see how this pans out. Brandon [/QUOTE]
