This isn't my first experience prepping brass in 223. Nothing went right 200+ pieces. Stuck the decapper pin in some H1 brass with tiny primer holes. Several times. Burnt up a old battery powered drill Dewalt 9v doing trim-debur-etc. still need to swage the primer pockets on about half. Finally stuck a case really good in the decapper die Lee. Tried hitting the stem then the RCBS stuck case tool but no good now letting it soak overnite in penetrating oil.
I need to re-think my prepping process for 223!
One good thing I cleared off a desktop and added space for case prep station.
