I have had good luck with 100gr. of loose 777 and the 250gr. SST's/TC shockwave (same thing). I get around 1" to 1.5" with this load. I am patiently waiting for some of my local strores to start carrying the new Blackhorn powder. It is supposed to give higher velocity, be non-corrosive, and keep better than others. I just don't want to pay the 20 hazmat shipping fee from the online stores that already have it. On another note, I have also had good luck with the various XTP bullets by hornady. I have tried the 45 cal. 300gr and 240 grain bullets using standard black sabots. Again, I am using a 100gr. charge of 777.
