I've been making smoke with my T/C Hawken .50 cal that I got earlier this month. I've been having trouble with accuracy and finally found a patch and figured out why it was so difficult to find them”¦they're shredded and burnt. I've been using 80g of Pyrodex, a .490 ball and .015 pre-lubed patches. I'm figuring I've got to go up a size in patches but am having trouble finding a good source of .018" patches, but can get .020" pre-lubed patches. My question is: will these be too thick or should I stick to .018"?
