Every time I have ever thought I had something figured out when it came to shooting I've had a gun come along and show me I wasn't so smart after all. Women too, but we don't need to go there. I got out this afternoon and shot the Pedersoli Bess. I was shooting from the exact same bench and distance (21 yds) and using the same powder charge, patches, and balls. I even used balls from the same batch I had purchased from TOW instead of the ones I cast from my new Tanner mould. I used FFg as priming powder because that's what I'd used in the India. I wanted everything as close to being the same as possible. There were three things that were different and beyond my control. The bore on the India Bess mikes .755". The one on the Pedersoli is tighter at .747". The India has a 39" barrel where the Pedersoli measures 42". The final difference was the weather conditions. Today was 90 F, pressure 29.77, and humidity at 67%. The winds were light and variable. No gusts to swat me around.
I decided to forego the paper cartridge testing. All I proved with the India Bess was that the stories about inaccuracy were true. I went directly to PRB. And I got a surprise. Take a look at the photo of the PRB group. It's nothing to write home about and much larger than the one ragged hole the India Bess gave me. The India Bess wins that one hands down.
Next I tried wadding with a bare ball and got another surprise. I ran down a wad of tow, dropped in the ball, and followed it with another wad of tow. I didn't even try to measure, weigh or otherwise be sure the amount of tow was consistent. The five shot group was actually better than the one I fired with PRB. See the photo. I think I hear Mario laughing from here.
All this tells me is something I've known for years. Every gun is a universe unto itself. I knew from the outset that the accuracy demonstrated by the India Bess with PRB would be hard to beat. I just thought the Italian gun would at least come close. I was wrong. Now I need to start working up a load for it that does. The first thing I'll try is lubing the patches. I've developed a technique that is sort of a reversal of the Schoultz "dry patch" idea. Instead of soaking patches in the water and Ballistol solution I've been using the solution as a bore wipe between shots. So instead of lubing the patches I'm lubing the bore. It obviously worked well in the India Bess but did it cause a problem with the Italian? I'll find out.
