A metal delivery nozzle (19) for delivery of molten metal to the nip between casting rolls in a twin roll caster to establish a casting pool supported above the nip. The trough (19) defines an open topped trough (61) to receive molten metal from a distributor. The bottom of the trough (61) is closed and the nozzle has side openings (64) and two large end openings (71) for delivery of molten metal from the trough (61) into the casting pool. The side openings (64) are longitudinally spaced circular holes disposed between unperforated end regions (72) of the nozzle.
