At the range yesterday and its getting to early evening time. Sun is just about set and im getting ready to go home. I start thinking about this guy that was shooting an ak pistol I saw earlier. It being full daylight I was able to see an enormous fireball of a flash and very loud report. So I say to myself I wonder what the flash on my .45 is. So I chamber a round and fire shot and notice I have a very large flash in low light conditions. In the day I don't notice this. I was using a 185gr plated bullet over a full charge of Bullseye powder. So troubled I ask myself I wonder if there is a low flash powder for 9mm and .45 auto. And now I ask you.
