I have a 358 Win built by Tim Malcolm. As per his recommendation I will be trying the rcbs 35-200 bullet. I believe he mentions 3031 powder working well for this, but for the life of me I cannot find data using cast and 3031. Target velocity is 1900-1950 fps. Along with that, where do you all find cast data? I have the Lyman book but could not really find what I was after in there. I looked at Hodgdons site, but it just showed a max load of 49 grains, no start load. I am thinking of starting in the 36-40 grain range, just making sure it was safe to do so
