"Back to patch material it can just be old clothes like a shirt or pants, sheets, whatever."
NO, no, no. Like Rifleman said, these sources of fabric give you fabric that has been unevenly worn and will yield patches of uncertain thickness. This will most certainly effect your accuracy. Use only new store bought fabrics of known thickness and keep your thickness consistent. Buy a micrometer, the ones that are shaped like a C clamp, and always measure the thickness of the fabric that you are buying to be sure that it is the same thickness as the last fabric that you bought for patches. Dutch Schoultz explains in his system the correct way to measure the thickness of fabric. In all things having to do with muzzleloading, consistency is one of the most important things in achieving accuracy. Grabbing cast off fabrics for patches for your rifle balls is not the way to go. It may be a good source for cleaning patches but not for ball patches. Remember, when it comes to muzzleloading rifles, three things to remember are consistency, consistency and consistency. :hatsoff:
