Dr. Thunder is the WalMart house brand of Dr. Pepper. I prefer it to the real thing.

Regarding the .22 Short Gallery ammunition, one thing the frangible powdered iron composite bullet does is spark when it hits steel. If you are old enough to remember seeing the old carnival midway shooting galleries, you might remember seeing several sparks fly when the bullet hit a steel duck, rabbit, or whatever the targets might have been. I would love to find a set of the old shooting gallery hardware to restore. I was at the NRA museum in Virginia around 10-12 years ago, and in it they had a restored midway shooting gallery. Of course it was just on display, you couldn't shoot on it.
