I have 380,000 rounds on mine. Mostly .223. Keep the collator bowl clean or you will have problems with bullets not tipping over properly. After awhile the bowl will get a copper shien to the inside. Brake ckean will remove it and not harm the plastics. The copper will make the bullet feeder act glitchy. I usually clean out the bullet feeder down tube every 5,000 rounds or so. Powder, bits of cardboard, staples, and misc crud are common when you buy bullets in bulk.
