Two more lubes tried

For round 9 of the Kent Black Powder League, I used the .350 Hornady lead balls with 0.015 Tanner patches lubed with homemade 1:1 Aqueous Creme:Water. The loading was very easy, and the swabs between shots showed that the soot was easily removed each time.

The down side though was that the patches were not being completely lubed. On most of them I noticed dry areas on the patches as they were loaded. I might try a thinner 1:4 Aqueous Creme:Water version of the lube next time.

The result was an 88.1 with three 10's scored. The group was fairly tight, although 3/4" low and 1" right. All ten scoring shots were inside the 8-ring.

For round 10, I switched to a commercial lube of Ox-Yoke Wonderlube on the 0.015 Tanner patches. I found the loading was slightly harder than with the previous lube. The final grouping was not as accurate as the R9 card though. I don't think I can blame the lube though; I'm just cannot cope with a second 30 minute detail, even after a break.

The card scored a disappointing 79.0 with some high flyers, although the horizontal grouping was very good. The swabs also came out fairly dirty each time, so I might try this again but with 0.012 patches.

Managed to keep the average above 80. As there's no more comp cards, will practise with lube development until the winter season starts.
