I have a Savage Model 11 (CF, 4.40" spacing. blind magazine) in .223 Rem that I converted to use CDI bottom metal and AI 10 round .223 Remington magazines. Having an issue with reliable feeding. In some cases the bolt slides right over the top of the round but in other cases it will feed without any issues.

Fair amount of vertical play on the magazine, but from talking with folks at CDI, that isn't unexpected.

Saw a comment previously about bolt head cross pin hole being an issue, but not following how that can cause the inconsistent feeding behavior I'm seeing.

I would suspect the problem is the magazine spring, but behavior isn't consistent on which round it passes over or which one it feeds.

Any thoughts? Is the bolt head cross pin hole possibly in play or something more obvious?
