There shouldn't be any problem shooting the 180's out of the WSM other than the OAL probably wont permit the use of the short action mag. I dont have any problems shooting the 210 Berger out of my 300 WSM
The RUM is a significant step up from the STW.
For comparison, the WSM and RM will shoot a 160 gr bullet about 3000 fps or so. With RL17, the WSM will probably beat out the RM and get 3100 +
The STW and Dakota will shoot a 160 gr bullet about 3200 fps or so.
And the RUM about 3400 fps.
The RUM shooting a 180 bullet will out run the EDGE ballistically to about 1000 yds. But the EDGE shooting a 300 SMK will hit a whole lot harder.
