I have a 50 cal Traditions flintlock with 1-48" twist. Always used RB. Killed one deer with RB and she ran 200 yds, hit in the gut. Thought I would try the 200 grain TC Shock Waves this year. I know nothing about them. How accurate are they? Can I use Goex FF? How many grains? Or are round [censored] better? Thanks.
