You might have to experiment with the ejector spring and get some spring stock from brownells and cut one a coil longer to give it the pressure it needs to eject that case with authority.Not ridiculous tension but a little bit more to help.Before you fire it afterwards make sure you can push the ejector down flush with the bolt face or you will have big trouble ,meaning the bolt wont close or it may and after firing it will extrude the cases and ruin them.If it is too much remove a 1/2 coil at a time with the new spring.Maybe sharpshooter will chime in with his most expert advice.He knows his stuff.
