Default Fixed! Update: Savage .17 HMR Model 93r17 Light Strike Misfire Fix?

From day one this rifle misfired and over the years it progressively became worse. The first thing I did was to changed ammunition, then warranty firing pin and magazine. Then after several years I recently decided to send it back to Savage under warranty. I sent them a written history with an explanation of the defects. They replaced the outside extractor and firing pin. When I got the firearm back it still had a light strike and failed to fire more often than not.

So after a couple of firing pins, magazines and an extractor I decided to diagnose the malfunction myself. I started by tuning the bolt face and firing pin, then disassembling and cleaning the bolt, neither corrected the problem. Then I added a shim between the bolt and bolt face, fail because that only moved the stricker away from the firing pin causing more of a light syrike on the cartridge.

Then after more function checks I isolated the defect at the bolt locking handle and the slot on the barrel. The worn handle and barrel slot has opened the head-space causing the malfunction. I tested this by using a folded match-book as a shim placing it between the bolt handle and the slot in the barrel, problem solved.

What is the best fix? I can think of several but wanted to hear from the experts, I'm a retired mechanic.
