I had a fabarm sp12 a few years ago I got a rifled choke for it it shot factory seller and ballot slugs to about 4" at 50m not sure if that is good or bad but was consistent. After an outing the choke was a bitch to get out. It seemed to get tighter and tighter, also it seems to foul badly with lead. Now I use an M2 with a fully rifled barrel and sabots.
