.40 Cal reloading

[M27]

I don't reload 40 but I do load 45. I have used a lot of power pistol though. Like already said power pistol creates a huge flash. The only thing I have found to create a bigger flash is minimum loads of longshot but with closer to max loads the flash goes nearly away. titegroup creates a small flash, AA#2 had almost no flash even with a light bullet.
