Snake oil actually works if you can find real "snake oil." But I've seen polishing compounds applied to bullets that is suppose to reduce and remove barrel flaws on new rifles. And lets not forget gun powder that reduces copper build up the more you shoot.Snake oil .....
Do they even say what shot size they are?
Thanks, the diagram showed what looks like a typical shot shell, pointing to a liner surrounding what looks like shot.No shot involved. The payload is scrubbing material, felt wads to pick up particles scrubbed out, a wad column designd to press the scrubbing material against the shotgun bore, with squegee disks between the scrubbing material, felt wads, and the wad over the powder charge, The gunpowder is supposed be super clean very low residue. Sounds like a great way to spend money and litter up a shooting range (as if empty plastic shot cups weren't enough litter).
Three types of Williams Patent bullets, also known as "cleaner bullets", were used by the Union Army during the American Civil War in the standard .58 caliber rifle muskets. There was a fourth developed for use in the Union Repeating or "Coffee-Mill" gun. The inventor was Elijah D. Williams of Philadelphia, Pennsylvania, who filed an application for his patent on May 30, 1861. It was issued almost a year later, on May 13, 1862, but field trials on his "improved" bullet had already begun.
The concept of the design was that the discharge of the musket would drive the concave disks forward thus expanding the lead bullet against the interior walls of the rifled barrel.
Right up there with the urban myth that shooting FMJ through a leaded barrel will clean it.
Also put me down as one who used to shoot a cylinder-full of warmish gas checked rounds thru revolvers at the end of a smokey cast/swagged shooting session. I think it helped with any leading that was there; maybe it was the placebo effect of actually doing something/anything about the issue.
Semi-autos... not so much (jacketed vs gas checked, of course).
Coyote's experience is obviously different.
