I tried to do two 10 shot groups with PRB’s and this CVA.
@longrangelead stated that this barrel had been left loaded for about 15 years. Due to the barrel issue, I cleaned it well and could feel a “ring” or really rough spot right where the bullet would sit.
First 10 shots would be without swabbing between shots. First couple went ok, the second load was only a bit more difficult to seat. But, at #3 it became very difficult to seat and only got worse. By shot 5 or 6 I had to use the tailgate to seat the ramrod all the way. The shots also got worse. Shots 7 and 8 didn’t hit the IPSC backer.
These were pre-lubed patches .015” thick and .490” balls. 65gr FFG Swiss.
Looking at the target when I went to pull it, the two balls hit the head. This continues the trend of it shooting way high when it gets Fowled.
I stopped at 8 as they were off the paper. Swabbed with spit patches and started the second group of 10 that were going to be swabbed between every shot. These were spit patches with .490” balls- 65gr FFG Swiss. Only made it to shot number 2, as the end of the ram rod came off-
Went home, put a bunch of super glue on the end of the ram rod (glueing myself to everything in the process) and shoved it back down. Got it out and continued today-
What’s interesting is when the swab patch was very tight at the breach, that’s when the shots were off. The times I swabbed and it felt much smoother, that’s when the shots were in the black (the first two shots after the heavy swabbing were both in the black). The nasty spot in the barrel was cutting the swab patches.
Then I tried the same .015” spit patch with a .495” ball, same 65gr FFG. While they were much harder to start, the tighter ball/patch combo did seem to help keep the fowling not so aggressive in the patches.
The group was significantly better, but again when the swabbing was rough and tight- the next shot was generally one of the lower ones.
I’ll keep playing with it until the Flintlock comes in, but the barrel needs some attention.
