Anyone done anything with a 20 ga fully rifled, other than Sabots? How about Truball in a smoothbore 20ga? I have a 20ga paradox (vintage) that shoots 500 gr conicals (NEI mold) quite well but I have to keep them at around 1000fps or they strip the rifled choke, even when hardened up a little. Trajectory is terrible. I did shoot an Eland with the gun in Botswana in 2002 and it was quite something to see 2000lbs of meat bite the dust within 40 yards of being hit.
