Absolutely not. We wouldn't even be discussing these loads if that was the case. I guess to say "sticking" to us was more of taking a nice little bump on the extractor with the free hand to get the cases to drop.

My recent Handloader has an article by Brian Pearce citing 12.5 grains as his load of choice. I'm going back to load some of those and see what I get.

Edit to add: These loads were worked up to, but not in this particular revolver. To be honest, I hadn't thought of the idea of working up loads to particular guns, outside of something like abnormally tight throats or something similar.
