A patch's purpose is to creat i perfect seal around the ball so that none of the powder power bypasses the ball.
If a person uses two patches he has found that his material is way too thin to create that seal but two times that thickness better serves his purpose.
The ,015 and .018 patches you mentioned are not those thicknesses when they are crushed between ball and barrel wall. When crushed tightly in the jaws of a micrometer you can see how thick that material is when in use. If you buy six different materials that measure .018 for instance and crush them one at a time with a micrometer you will probably find six different measurement usually a boy 60% as thick as the stated measurement from seller.
Getting that perfect for your rifle can give amazing results. In my experience. Pyrodex is OK for percussion rifles but requires extra care in cleaning.
Why did you switch from conicals?
