I’ve been tweeting a percussion rifle with the help of the members here and I appreciate that. I’ve been changing one thing at a time and finally got groups at 50 yards, although 3-4 inch groups (5 shots). First I noticed the store bought CVA patches that say .015 are loose. Measured they are .009. Then I tried Ox-yoke .015. Also loose, they measured .011. I could not find a single one of these patches downrange. Switched to blue stripe pillow tick from Wal Mart that measured.019. Good fit. These patches are where the groups came from with .490 ball, 80 gr T7 FFFg. These patches are burnt and shredded. One even smoldered on the range and we had to cease fire so I could stomp it out. I tried Ox-yoke wads and saw no difference in group size but could not find the patch to assess. The patches were wiped on one side with SPG. I am seeking opinions regarding keeping the patches from burning. I have cut 3/16 cork wads lubed with olive oil and beeswax. I have fresh pillow tick patches cut round with thorough soaking of melted SPG and square cut soaked with beeswax, olive oil and T/C lube mix. I am not opposed to cut-at-muzzle and may try that with some kind of lube. Please, help me save these patches and tighten those groups. This is a percussion rifle that was pre owned and has a few hundred rounds through it.
