I had almost 50% light strike issues with a new savage 30-06. After reading thru multiple forums I decided to take apart the bolt. Here is what I found
.
The Savage Axis appears to use a two piece spring separated by what looks like a metal O-ring. When I took the bolt apart I found that the O-Ring was captured by the rear spring--my theory is that as you cycle the bolt, the rotation randomly causes the open end of the spring to capture the O-ring (or equivalently lock into the O-ring). This effectively reduces the spring tension since the overall length of the spring mechanism is shortened.
Given what I heard about delays in getting it fixed, my solution was to take a hardware store washer and grind/polish it down to the appropriate size as a replacement O-ring--keeping the outside edge square. (Note--the the washer is round, just the outside edge is not rounded). That way the spring does not get a chance to climb into the washer. I also made the washer 20% thicker (tried 50% initially but the bolt felt tight).
Since that modification I have not had any light strikes.
