Not knowing what the gun was but it sounded like the gun that shoots 410 and 45 acp (not the Judge) and someone shot a 45 long colt in it. It blew up.
  • .45ACP operates at significantly higher pressure than standard .45 Colt, 21k psi vs. 14k psi. If it can handle .45ACP, it can handle standard .45 Colt without problems.
  • I'm not aware of a .410 revolver on the market that can't handle .45 Colt, as a .410 shotshell is substantially longer than a .45 Colt cartridge. (The S&W Governor has a minor limit on loading more than one type of ammo at once because the factory "1/3 moon" clips HAVE to be used to load .45ACP, but it can handle all 3 ammo types in the same cylinder.)
  • AFAIK none of the .410 revolvers on the market are rated to handle .45 Colt+P factory ammo or "Ruger Only" handloads. This ammo has a max pressure of 27.5k psi, well beyond .45ACP, and nearly double standard pressure. Perhaps this is what has you confused.
Besides, there are all sorts of ways to blow up revolvers with a variety of ammo-related mistakes, but there's no way we can definitively conclude what happened in this incident without more information. (For instance, the shooter could have fired factory .38Spl+P from an ancient S&W without a heat-treated cylinder.)
