I own a Redding UltraMag. I use it to reload my 470 NE. I does an excellent job, although I prefer my Rockchucker for most of my reloading. I can access the round I’m reloading from either side with the Rockchucker. The UltraMag boxes the round in and can only be accessed from the front. Ergonomically the Rockchucker wins for me. That being said, I’m not loading more then 20 or 40 rounds at a time with the UltraMag, so it’s not that big of an inconvenience.
