I've owned one 300 RUM and a few 300 Win Mags as well as a few 300 WSM's. The RUM I had was a Rem 700 LSS without a brake and I didn't think the recoil was too bad, but I like that I can get away with a lighter rifle in the Win and WSM with very manageable recoil. To me they are about ideal for elk and moose, especially when hunting in griz country. They also make great deer cartridges. If I had to guess I'd bet around 75% of the deer I have taken have been with one of those 2 cartridges.
