I used it yesterday for the first time to actually load 50 rds of 357 and all worked great. I had maybe 2-3 primers that did not go into the cup, but none fell on floor, it just didn't feed one. Might have been my fault, not push far enough in to drop one in cap. One was to low (last couple primers) and did not feed as people have mentioned, but overall, it did great and made some nice rounds. I am quite pleased with it. trikerider
