I have a Thompson Center 50 cal Hawken. I've only shot it about 30 times and my accuracy was less than stellar. I think my .490 ball & 0.010 patch is too loose. I'll be trying a 0.015 patch next time out. I've read where people are doing what they call a spit patch between shots...I'll try that too. Right now I'm using Pyrodex powder, should I try 777? Does anyone have any accuracy secrets they'd like to share? Thanks in advance!
