There is a very basic Legal Maxim: "
He who asserts must prove." You don't have to be around firearms very long to quickly understand that
all firearms can be destroyed if misused. Savage Arms has made smokeless firearms for how many years? Most every 12 ga., 20 ga., 28 ga. .410 bore that goes bang every day (
with comparatively paper-thin barrels) uses smokeless powder. A 209 primer, wad or sabot, and a slug or shot-- all old news. Loading from the muzzle changes nothing, assuming the gun is designed for the recommended propellants and loads.
This is fairly old news: this article covers what you need to do to damage or destroy a 10ML-II. It isn't easy; you really have to work hard at it any ignore the many printed safety warnings (
and common sense). If you really want to and try hard enough, it can be done.
