Today I was at the range and every thing went very well except I had something odd happen with my 9mm. I was shooting 4.1 grains of green dot over a 356242 / 120 grain cast boolit out of my glock. (I'm aware of the polygonal barrel vs cast) but have shot a boat load this same boolit through this pistol but recently switched to green dot because of powder availability. I only had one, nothing seemed different. I just happen to notice because the brass flew up straight and landed on my sleeve. In total I shot 50 rounds and this is the only one that Did this. Any thoughts?
There is a small dent in the cartridge where it looks like it hit while feeding. It really appears it wasn't fully seated when it went off but I was shooting one round at a time at some steel but hopefully someone will be able to shed some light on this. Also the primer seemed to be fully seated.
