Anyone tried one of the new calibers?

The Remington ultra mags have been around since 1999 and I believe are still going well. I know a lot of people that own them, one guy who owns all the RUM series. I recently had a hard time finding brass for my 300 RUM since all the suppliers were sold out. As long as they make brass for it, I will be happy. I personally haven't had any experience with the SAUM's, but have heard that some guy's like them because they kick less. My 300 RUM kicks like a mule on the bench, but when I have a deer in my sights, I can't even feel it. I think everyone is like that though.
