I think I need a thicker patch, though. In the T/C they recommend a .490 RB and a patch, but don't specify the thickness.
There is a good reason why you are stating that you need a thicker patch. What might that be? The Patch-Ball-Barrel combination, is mostly a personal choice based on you circumstances and that is basically how TC lists this. However, if you look at their loading table/data, it's based on a .015 patch. This is always a good place to start and see where you land from there.. ..
As far as pillow ticking
, just Google it and you will see a list as long as your arm. Many fabric stores carry this as well. ...
