When I try to unload, the casings are stuck in the cylinder. With enough effort, I can get the rod to move and drive them about halfway out, but they won't drop out. Each round has to be pulled out by hand. Brass cased ammo has no problem. And since the rounds drop in so easily, I'm assuming that the casing is expanding after it's fired. I've used Tula before for rifles and in 9mm, and I've never encountered a problem like this before. Has anyone else had a similar problem - in .38 Special or another caliber? It certainly put a crimp in my range work today, that's for sure!!
