I worked a gun counter for about a year after I retired and saw some really dumb stuff, but the dumbest was an old guy who came in and said he wanted to show me something. I said OK and he asked me to pull a Taurus Judge from display. He then picked up a box of .444 Marlin ammo and asked me if I knew that it would fit the Judge. He wanted to load the gun to show me. I refused and told him that although it might fit, it was a dangerous thing to do. I told him that the rifle ammo was loaded to about three times the pressure of the .45 Colt the gun was designed for. I believe the only thing that saved him was the smaller diameter bullet, which let a lot of pressure blow by.
