I was using them in a .22 Sharp innova and from what I remember the accuracy was not bad although as I said they were very visible through the scope sort of taking a corkscrew flight but still hitting my tin cans. If its fine tomorrow I will get some out and shoot some at 25 yds and let you know the group size. I found out in the end that one may as well buy some heavy weight pellets like Bisley magnums and save the hassle of making them.
