UB,
I have and love my TC Encore 50cal. I started out with 150gr of pyrodex pellets(50gr) and a 300gr sabot. Couldn't dial it in to save my life. So, I switched over to 777 pellets. Put my old Simmons shotgun scope on it and had it bore sighted for me. Took it to the range. First shot w/o adjustments dead center @ 100yds. Second and third shots were the same, stacked on one another. I have not touched the adjustments on it at all in the 9-10yrs I've had it. Furthest shot to date with is roughly 225yds offhand.
