In my Impact along with BH209 at just 70gr by volume I use Hornady 45cal. (.452) 250gr HP/XTP's with Harvester Crush Rib (black) sabots and Federal 209A primers. VERY accurate with good performance on whitetails. BH209 works best when compacted well. I give the load 5 firm hits with the ramrod. This combo of components was recommended by numerous shooters. In fact except for the use of red sabots instead of black the same load works just as well in my SIL's CVA Wolf.
