Look at that, you are right, no data for anything heavy with Unique. Don't ask me why, but I started at 6.5 gr and worked up. Stopped at 9.5, wrote down there were pressure signs. I didn't do anything scientific. I probably had a beer or two and picked 6.5gr as a starting point out of thin air. I do not recommend this procedure to anyone.Ok thanks. Lyman does not show unique for 300grain projos.
