RE: Bullets for a 50 cal Hawkin TC replica
I've been using a houseful of TC Hawkens for years, patched round balls are outstanding in them, and are all I use anymore for year round practice and deer hunting every fall.
50grns Goex FFFg (or 70grns PyrodexRS) - Target loads
90grns Goex FFFg (or 120grns PyrodexRS) - Hunting loads
Oxyoke wonder wads
.018" TC prelubed pillow ticking patches
Hornady (or Speer) .490 balls
