Given that the weather forecast calls for things to turn cool again tomorrow I decided to get the next stage of accuracy evaluation done today. Today I had 68 degrees, humidity of 64%, wind of 10 mph almost directly in my face. Once again, the range was 20 yards, 75 gr FFg, and .600 round ball.
My first group of 5 shots was using a patched round ball instead of the shotgun wads. The result looked so much like the one with wads that I didn't bother taking a photo. It's obvious that either method of loading produces equal accuracy. I moved on.
The second group was fired using tow. I poured in the powder, ran a wad of tow down, dropped in the ball and ran another wad of tow down to hold things in place. This method of loading gave very good results in my English style smoothie. The results were not so great with the Dutch.

The group is more rounded. Not bad but not as good as with shotgun wads or PRB. I also had to keep the water hose handy. The smoldering tow started a small grass fire!
My last experiment for the day was substituting FFFg powder for the FFg I'd been using. Using the same powder measure throwing 75 grains of FFg, I loaded with shotgun wads. The recoil was more substantial but group size remained roughly the same. I guess either one will work. I did note that there was less fouling in the form of unburned powder granules with the FFFg.
That's it for today. Wishing everyone a Merry Christmas!
