MG34 ejector issue

Has anyone seen this before? ejector? booster cone? I just replaced my 9.5mm with a new 11mm and fixed the feed jamming issue, now I have this problem. Here is a pic, a spent case turned around and fed back into chamber and a new round fed in a same time.

a couple of maybes:

Not enough recoil to eject the empty from the bolt path,

A common occurrence before it was figured out - the shell bounced down and then back up. That's why the newer lafettes had a deflector plate.

Thanks, I have a 9mm booster cone and a new 11mm. I was using the 11mm. I will drill out the 9mm to 10mm and I have also installed a new (TNW) ejector. I hope I have to ground too much off the back for clearance. I use a dummy round and chamber it then manually cock the bolt to get the ejector action. It seems to work. Will have to try the range again soon. It's getting close.

I installed a 10mm booster cone and get the same empty case jam. I also replaced the ejector pin with one from TNW. I may have taken too much material off the ejector pin when fitting it. Does anyone have a picture of the proper fit of a ejector pin with a cartridge seated in the bolt face?
Thanks, CT

Old thread I know,

But my TNW semi is having the same malfunction. Haven't measured the booster cone yet but, I am curious as to how you fit your ejector.
