I did it with my $150 45-70 rifle I bought a couple weeks ago. The springs aren't strong enuff to push out a stuck case. You gotta be sure to polish the chamber good and keep it clean. ...which I need to do on this new rifle.
.
I polish the chamber with #800 grit and follow up with 1200 grit wet and dry cloth lubed with thin oil or penetrating fluid. A strip of paper is inserted in a slit wood dowel and spun with an electric drill. The Flitz and J-B paste job does not really smooth the chamber it makes it shiny and it helps in most cases. I found it inadequate. But you need a 20x bore scope to tell.
The get a bit more spring pressure on the ejector. I put a smaller spring inside the main spring and put a #2 or a BB (.150 -.160") steel shot into the spring race way with the spring on top of the steel shot. It helps with stuck cases.
You have to give the ejector a mirror polish on the rounded front part so the ejector rides smoothly over the case into the groove. Works pretty good on two of my rifles.
I found that with multible reloads the cases loose their spring back and will stick. With full sizing high pressure cartridges like the 243 and the 25-06 will only last 8-9 reloads and then show signs of case separations. Same with my 257 Roberts. I started with 50 new brass and discarded more then 50% sofar. When going after game best use new brass, or factory ammo in a Handi.
Case separation are not gun friendly for several good reasons, for one they blow all sorts of dirt behind the ejector and leave a stuck case in the chamber. All around bad news.
