I like One Shot, but one thing I did notice while using it. Before you spray them down, I use an old cleaning kit brush and run them down the neck to clean anything that may be in there. It helped me for sure making sure I didn't get a case stuck in bottleneck cases.
Example: for my .223 cases, I use an old .22 wire brush from my cleaning kit and run them in the necks of the cases. Then I spray them down with the One Shot. Doing it this way I haven't had a single stuck case.
