Welcome to the site.
Ejection probelms are commom on Savage rifles, and depending on caliber some are more prone to it than others, So it is not just an Edge/Axis problem. If you paid this gunsmith and it is not working I would take it back to him. My guess is this smith is not use to the Savage rifle, because what he did would not fix the problem. The problem lies in tolerances. Some of the bolt heads are bigger than speck, and some brass is smaller than speck. With a combination of both it can amplify the problem. Most times the problems can be fixed with changing out parts. I would first start by placing a larger ball bearing (.140) behind the extractor.

As mentioned in the post in the FAQs section above, you may need to have a new bolt head made, or a custom extractor made. Sometimes people have gotten new bolt heads and fixed the problem.
On the ejector, I would replace the stronger spring for the factory one. The ejector can be lengthen and this works well with short cases like the PPC and BR when using them in a Savage action. I would also flatten the contact end of the ejector, because with the rounded end the case has the ability to roll off and not eject.

When lengthening the ejector, a longer Factory rated spring will help, but it is not necessary. I hope this help you out.
