I did once, never do it again. A friend gave me a box of soft point .223's for Deer hunting. Loaded up my trusty AR-15 and got a pop!, not a bang. Pulled the bullet and found no powder. Now curious, I pulled the bullet on another round and found a LOT of powder. Disposed of the box. What if the second round had been fired first? I was at the range when a co-worker was shooting a S&W 4 inch .357 Magnum and hit a bad reload. Cylinder and frame wrecked. He got the re-loads from a friend also.
