I've heard the "unburned powder" in shorter barrels argument for some years, but it occurred to me that if there was any of this unburned powder spewing forth, there would eventually be mounds of the stuff piling up just past the shooting benches at rifle ranges across the land.
Unfortunately my plan to recycle all that free powder just doesn't pencil out in the ROI column.
