Anybody know the diameter of patches or patch cutters for patched round ball rifles? I've only got two cal. present, a .40 and a .54 with a .45 I'm working on. I've had good results with pillow ticking, but I'd like to turn a cutter to make precut patches.
Any ideas? I've thought about just getting the fired patches and measuring them, but patch material stretches and gets frayed on the edges after firing.
Thanks
