I have five TH feeders. None of them reliably throw a mixture of LMB and BG feed from Optimal without jamming every 2 to 4 weeks. Even when the aperture was widened, still problems.
My experience inclines me to hand throw anything much larger than 4.5 mm. Unfortunately, I don't live on site so this limits my program considerably.
Also, using really small feed for YOY BG invariably sticks together & sets up in a block during warmer, humid months. Might be able to avoid this problem with bottom type feeders, but huge problems with broadcast.
Maybe others have the magic touch, but that's been my experience. Another fish feeder company advertised a feeder that would throw 1 inch(!) pellets, but apparently that didn't work out because those ads quickly disappeared.
Wish my feeders could throw 1/2 inch LMB pellets without jamming -- my HSB go nuts for it! -- but it hasn't happened.
