Tracy, IIRC the Sweeney is rated to 1/2" pellets which is all I need. I only hand feed my 20 HSB Optimal hand throw or Purina LMB pellets because they disappear and show back up at the most random times. I fed them twice yesterday, and they ate almost 5#'s. Today, they didn't show up at all. I can't bring myself to dedicate a feeder to them knowing that, but I'm here on the property so it's much easier for me to feed them by hand.
Bob L has, or had, an Avenger so maybe he's tried the larger pellets and can be some help.
