RE: TC Renegade .50 Question
PRB with 80 grains of Goex FFg with a wonder wad. Same load worked well with Maxi-hunters. The wonder wad was really what made a difference for me with accuracy with both PRB and the maxi-hunter. Before the wonderwad my groups were huge and inconsistent, afterwards they shrunk to one to two inches at 50 yards and were consistent. Good enough for me and the deer that I shoot.
Experiment with powder type, powder amount, and projectiles. Try different variables (with and without a wad) and document so you know what works in your gun.
Good luck.
