I have been loading on a progressive of one kind or another since 1966. Have I messed any up..sure have but I always caught the foul ups. They were ALWAYS my fault..and I always caught them. Most recent was a couple of years ago. Loading 45 auto with 231 at 5.3 gr.. That machine has been set for 5.3 of 231 for3 years. I had to add powder (from a different lot) and shazam the powder charge went from 5.3 to 6.6 gr. Luckily I had dumped the loaded rounds and started anew. Loaded 91 rounds when I did a powder weight check and caught the overage. messed my mind up for a bit. Dumped the powder and got a match of the original lot number and it was back to 5.3 again. Don't know why...but has never happened again. I always check when using a new can of powder same lot or not. When loading on a progressive I never load maximum loads especially in mag handgun rounds.
