I have an encore seem to like more powder by best groups are with 110 gr of t7 3 f and a 300 gr xtp or TC sst. How is your trigger pull some encores are heavy that can effect accuracy also. I also shoot goex pinnacle 3f I use 130 gr of that. I think that TC recommended load is 3 t7 pellets and a sst 250 gr. I have a few spots I use the encore mostly for open fields. I got the flintlock bug this year and have basically spent my time on them.
