For all the years I have been shooting muzzleloaders, I have used store bought patches. My Hawken rifle liked the .015 patches and just a tap or two on the short starter then ram her home. While at Walmart, I decided to try making my own patches and have read here that most of their pillow ticking is.018, which I have tried in my rifle and you need to hammer the ball in with those, so I picked up another densely woven fabric that felt about right to try out. I don't own a caliper and wouldn't know how to read one so the feel test was the best I could do. Washed the new fabric and let air dry, cut off a strip and went to the range. I just spit patched them and the first ball, I could push into the barrel with my thumb. No short starter needed. Well, this was not going to work. The patch was too thin. Imagine my surprise when I had the most accurate day my 60 year old eyes have had. I was taught that the patch needed to be tight for the ball in engage the rifling. Guess my rifle has other ideas. :wink:
