Ok, I bought a 10FCP McMillan and converted it to the CDI DBM kit. The problem is with the Accuracy International (AI) magazine. If I load a full clip (5rds) and insert it, the first round chambers correctly, but the second wants to nose down under the feed ramp when I close the bolt. The follower or spring is binding up at the front of the magazine and the cartridges are only being supported in the rear. This allows the bullet to "dive" under the feed ramp as the bolt is closed. When this happens I can usually plunge the cartridges a couple of times and they will eventually pop up tight and feed normally. This problem only occurs on the second round.

I'm sure the fault is not in the CDI kit or the installation, because it doesn't matter if the magazine is in the gun or not. I can push the rounds out of the magazine by hand and the same thing occurs. Anyone ever had this problem? Does anyone have any suggestions?
