As you know, there aren't any rules that are set in concrete when it comes to reloading, but normally a load for a heaiver bullet can be substituted for a lighter bullet of similar construction.  That means a 300 gr lead load can normally be used with a lighter lead bullet.  Of course, if there's too big of a difference in weights, you may get into an overage in the velocity department. 

More than likely, a 12.0 gr of Unique/Universal/Green Dot load would be a mild load that may break 1300 fps, but would probably shoot pretty good.  Somewhere around 16.0 gr of Blue Dot wouldn't be too much velocity either.  I shoot 20.0 gr of Blue Dot with a 300 gr JHP, so the 255 gr lead with a lesser load will probably duplicate the 1470 fps I get with a jacketed bullet. 

Start light and work your way up.
