There can be some wear to the
left side of the center pin hole which is normal wear. This does not constitute an oval hole, just superficial wear as the center pin rubs over the sharp corner of the hole when the cylinder is closed.
If there is wear to the
right side of the hole it is from the cylinder being closed too forcefully causing the yoke to flex and allow the center pin to bypass the hole and then drop in as it comes back to the left. This is always accompanied by burrs on the right side of the ratchet recess in the breech face caused by the ratchet striking the step when it goes past where it should normally stop and lock.
Neither one of us knows if the OPs gun actually has an oval hole or simply superficial wear to the edge of the hole. I take him at his word that it is oval. By the time the hole actually WORE oval under normal use it would be thoroughly worn out in several other areas.
