I poked around a bit and didn't see a forum specifically dealing with this topic, so I'm offering this as a "share as you will" topic.
I don't have a reloading setup, so I was looking for reasonably priced sets of dummy rounds to cycle my Rossi actions without firing them in the house or having live flying ammo lost under the couches.

Here are the nicest dummy ammo rounds that I’ve found on the internet, next to making them up myself. And, the prices are way more reasonable than the ABS/plastic ones sold by a lot of places. http://www.dummybullet.com
