OK, this'll be directed mostly at James, but maybe others would have input too? I've ordered a Lee .600" round ball and plan to make up some tri-ball loads, as James Gates has described, using hard cast balls. I ordered the BPI Multi-Metal 3" wads with a .045" wall (http://www.ballisticproducts.com/pro...number=3221230), which do not have a cushioned base. Is a .25" cork wad acceptable for a cushion? Or maybe I need two cork wads?
Also, I saw a post recommending to start with 28gr Blue Dot for this load. Can anyone verify this? If I "start" with 28gr, how much farther can I go?
Thanks in advance.
