Longbow,
The full bore Brenneke clone was used for those groups. The sleeve slug is less accurate, but not all that much, about 4" at fifty yards, where the clone will do 3" or less. So far, I have not tried the sleeve slug at ranges over fifty meters, except for the large meplat slug which started to tumble beyond that range. Since the large meplat slug mold had been re-cut from the original mold, I had to make a new mold with the original nose profile. Extra work I know, but you win some and you you lose some... I still hope to improve on the sleeve slug by tinkering with the nose profile.
