It's not sticky, it's freaking jammed. cylinders have been cleaned and cleaned and cleaned prior to firing. Been brushed out with a brass cleaning brush and the rounds literally fall out when not fired. When fired they expand so bad they jam. I've compared the fired to unfired and you can see the expansion of the end of the round where it fits into the barrel. When you get the ejection rod all the way to its stop, the round then falls out. As soon as I order some other ammo I'll give it another try, but it's rapidly becoming a display piece never to be fired again. Plus, the round is pretty useless as a self defense round as far as I'm concerned and only good for shooting paper targets, which would be fine if I didn't have to beat the rounds out to unload the thing.
