End effectors with increased clip loading capacity include a housing having a tapered section at a distal end; first and second jaw members protruding distally from the tapered section; a surgical clip feeder arranged within the housing and configured to contain a plurality of surgical clips therein; and a feedbar longitudinally movable between the housing and the plurality of surgical clips, the feedbar having a distal portion engageable with a distal-most surgical clip of the plurality of surgical clips within the tapered section. The plurality of surgical clips is arrangeable within the surgical clip feeder at a non-zero angle with respect to a longitudinal axis of the end effector. Actuation of the feedbar engages and advances the distal-most surgical clip out of the surgical clip feeder and into interposition between the first and second jaw members.
