I just purchased a new TC firestorm .50 flinter, with it I also got cans of goex 2f/4f, pre-lubed .15 patches, .490 round balls, and some .350 maxi hunters. Headed to the range tomorrow and looking for some startin points on powder charges and distances I should shoot at. Also i have shot/loaded flinters in the past but first time owning one.Thanks in advance.
