Daryl,
had a think about sighing error, first shot was a bit low, then made sure is took a ver full sight, its a bit tricky I now realise as the sight notch is a little wide, still the same load as before, as I have not greased up some more patches. I did not have to wipe between shots as she really likes the greased felt wads. I did knock the rear sight a tad to the left and now she is truly shooting to POI. Next time will try a different patch lube, the bore continues to improve. I won't increase the powder charge, I am at the limit of my powder flask, but may consider working up some FFg charges. I do find the Fg ver comfortable even off the bench. I guess I am a bit windy about using the finer grade of powder.
