I recently bought a Uberti baby rolling block in .22 Hornet. The second spent cartridge would not eject and four of the next eleven had to be tapped out with a 3/16 dowel. The twelfth cartridge seperated up by the tapered shoulder and stuck in the chamber...this is when I took it back to the local gun shop and they have sent it back to EMF in California. There was a grab mark on each case on the neck. I'm now waiting to hear back from my gun shop. Has anyone else had a similar experience? How does EMF stand behind it's products? What can I expect?
