400, 500, and 600 feeds fine in my Moutrie feedcaster commercial. The AM LM is what caused the self destruct...it says not to use feed that big in the manual but I don't trust manuals (ever heard of the guy trying to use the bathroom in his RV while cruising down the road?)
The slide gate jammed, the metering auger broke the lower unit away from the hopper. Duct tape, super glue and some zip ties fixed it. It's was running fine for a year...until it got blown into the pond a couple of days ago. Waiting for it to dry out and going to see if the battery will charge before trying it out.
