My Omega likes the Harvester Crush Rib .44/50 for .429 bullets like the Deep Curl. It likes the Harvester smooth side EZ for .430 XTP's, and seems to shoot a variety of .45 bullets with the Black .45/50 TC sabots. These TC's may be a copy of the MMP standard black sabot. Blackhorn 209 with CCI magnum primers work well with all of these.
