IMO the 30 cals are the way to go.
I am a strong advocate of the 300 WSM
. It can be had in a short action vs a long action RUM or 300 Win Mag.
It will run a 180-200 just behind the Win mag and less than 100 fps difference under worst circumstances and mostly very very close. THe WSM shines with the 180-190 gr bullets and those are more than enough. RL 17, and H4350 with standard LR primers
It has 2-3x the barrel life as a minimum and practice is the key in LR shooting.
Just change bolt heads on the 200 and go for it if you want to use yours.
However, my first choice would be to go to Fred Moro at Sharp Shooter Supply as he stocks timed and tuned actions already to go, plus chambered barrels and stocks so you can put together a really great shooting gun for much less than some others and faster.
Look at www.savageshooters.com
forums also for info on all savages and maybe even barrels and guns ready to go for a good price.
Darrell Holland sells the Holland Radial brake that is absolutly great for recoil, but with the WSM I would not use one. If I went the RUM route, get one for sure.
