Bellydeep,
Yeah, I'm guessing it's going to have a sharp recoil. I shoot 300 RUM frequently, but that rifle weighs quite a bit more. Do you happen to reload your 200gr AB's? I have a solid supply of those already.
Yes, I reload for mine. 4831 or RL-22 work nicely.
If you’re shooting a RUM the WSM shouldn’t be a problem.
