I have used Bulls Eye for 9mm, .40 S&W, and .45acp so far, but decided to try some "flammable dirt" (Unique) because of how well it was received here. I was surprised how 6.5 grains filled the usable portion of my .40 S&W cases after seating 155 grain Hornady bullets. No double charges with this stuff.

I used Lee dippers for my initial trials. I hope it meters well in my Lee Perfect powder measure.

Now I have to go out and shoot the 10 I made up.
