I just purchased the tc pro hunter fx with 3-9x40 leupold ultimate slam. Im planning on shooting hornady sst low drag 250 grain with blackhorn powder. Im curious if any of you have any experience with this or similar setup shooting blackhorn. The scope is setup to shoot either two or three pellets (100 or 150grain) and im curious what that equates to in blackhorn powder. I would like to know about what setting I would apply for 100 grains by volume of blackhorn.
