A pompous ignoramus leading the blind. Why, oh why must everyone with no double rifle experience assume that the barrels will inexorably cross-fire at some predetermined range? A quality, well-regulated double will not cross-fire with the correct ammunition. If it does, the wrong load is being used or the rifle is out of regulation and needs re-regulating - or it was of poor quality to begin with. This guy is an armchair theorist.
