many guys don,t realize that the original mini ball partly stabilizes by being distinctly nose heavy / weight forward , just like a styro-foam coffee cup with a couple table spoons of sand in the bottom, if you throw a styro foam cup with a tablespoon of sand in it,it will always travel bottom forward, and wide open mouth to the rear in the arc it travels, the rifling imparts some spin increasing accuracy, but unlike the newer bullet designs the original mini does not totally depend on that spin to remain point forward, many newer designs are longer and not as nose heavy so they require spin to maintain gyroscopic stability.
but if the skirt is deformed as it exits the muzzle, or the mini is not spun by the rifling, any chance of a consistent shot to shot impact point is destroyed
