It was a huma duel port I think this is why I couldn't keep consistent speeds or accuracy and I think the center guide was broke for quite a while before it finally gave out
Yup, I rammed a slug down my transfer port once too. It was more than difficult to get the barrel out of the gun so I could remove it. The slug sheared as I pulled the barrel. That was back when I tried to use the FX pin probe with an elongated stock transfer port. I had no troubles with the stock probe so put it back in.
I thought that the dual hole port with that little bridge in it would stop that from happening. But I guess not always as not much of a bridge it has.
The barrel was stuck too and instead of pulling on the barrel until I broke it more I closed the chamber and pulled the trigger and that forced the slug out. Right or wrong it worked
