I am new to Berger bullets, and am trying to find some answers. I am trying to find the magic load for my 300 WBY with 210 VLDs. I am using H 1000 and Retumbo. I started out at 3150 fps and the MOA was close to 2.0. After half a box of lead later, my load seem to work well at about 2900fps. MOA is close to .250. The bad thing is the only distance I can shoot at is 100yds at this time. (Dam Canadian winters.) I have been tinkering with the COAL and from 3.550 to 3.900 it makes no difference what so ever to my MOA. I will have access to our range out to 800 yds soon. Does COAL make more of a difference at the longer distances? Or is this to do with the WBY freebore? Thanks for any input.
