OK I bought this beautiful S&W .357. A model 19-5, a real nickel plated number, with a 5" barrel. Fired some Remington 150 grain full metal jacket ammo. All is good. Bought a bag of frangible rounds with stainless cartridges at a gun show from a local guy who loads ammo, a pretty big player. This guy had probably 250,000 rounds at the local gun show. All cals, bullet sizes, etc. At any rate, I bought a bag of these frangibles. Took the handgun to the range. After double checking my varmint gun, went to the 25 yard lanes. The frangible rounds fired great. Clicked the cylinder open, and the cartridges are STUCK! I managed to push them out with a screw driver, but that's not optimal! I thought, "well I'll be darned, these dang cartidges just aren't coming out, I got ripped off. Word to the wise. I am a metallurgical engineer by education. I made an assumption that the stainless would be atleast as strong as the brass. But that was a bad assumption. But from you experts out there - is it in general a bad idea to use stainless cartridges in this circumstance, or is did this guy supply me with inferior cartridges - like thin gage steel for the cartridge? Any help is appreciated.
