No. Only the two peice hulls. Small bore hulls are fine. But the ones with a seperate base wad have been reported to be a problem. Many a post over at trapshooters.com on this issue. Most feel if you use a MEC type machine, which forces a loose basewad back down, you are OK as long as you check the bores between every shot. A few just do not want to take any chance as other good hulls are avaiable and use them instead.
