r9SC - Sorry about the pic sizes. I guess I've gotten used to the auto-resize that IE often does.
Woodstock - Actually, I like the Thunder 5 a lot.. but I've developed a longslide itch that needs to be scratched.
IMO, the Thunder Five is worthless in the .45lc, but the .410 is actually quite decent. Good spread at 10-20', enough velocity to embed birdshot in wood at 25', despite some reviews I've read.
In many ways, I think it's an ideal gun for people who hate guns, but want something around for protection against wildlife and non-armed people. This gun is loud, huge & intimidating, relatively low recoil, has decent spread and velocity at most person-to-person distances, with almost 0% chance of overpenetration.
The drawback is that realistically, you need to cock the hammer before firing. When you watch the videos of the guys on the site shooting .410 rounds, notice that most of the jerking is caused by the guys yanking on the trigger, not the recoil of the rounds.
