So, I assume there is some issue with trying to load a bare case into barrel from insertion in the magazine.

I have never had this issue in 223 and two other calibres I reload for.

I think the next step in this saga is to size a small number (5) and load them, I'll then try them in the magazine and hopefully they should chamber and load and eject ok.
I'll then take the rounds to the range and fire them and see the result re chambering etc.

Thank you very much for your help Loiner, I appreciate it.

I'll update after I've tried this, but it could be 10 days time as heavy thunder storms for this Wednesday at the range.
Hi, has it occurred to you that your rifle chamber might be at the bottom limit ? Also your sizing die to. Quick fix would be to grind 0.010" off the top of your shellplate and resize.
