I am just getting to know my 98 mauser, re-bored to 35 whelen, I have a few threads going on it with a chamber cast, another on 38/357 boolits and then the 250grain Cast Bullet Engineering mold from Jim here in Australia:

I am now just waiting on a chronograph to get an idea about velocity with my 39.5grains AR2206H (H4895) and 40.5grain loads, then I need to play with OAL to improve accuracy a bit. Best so far is 4" groups at 100metres, would be happier if I could get this to 2".
I have AR2208 (varget) on hand however am less confident using this for reduced loads, I wonder if it is getting to the slow end of the burn rate? I have read of RL7 being used for the lighter loads like the pistol loads, The Lee Modern Reloading has this for 158 jacketed.
Lyman 4th Ed gives data for 198grain and 3031 and for the 204grain boolits 3031 and RL7, nil varget data for those loads.
