40X bolt problem

[wisconsin]

After 50 rds my bolt starts to get harder to close. If I remove it and re-oil it. Its ok for another 50 rds or more, Than it happens again. I've been cleaning/lubing it with Gunzilla. Could I have a spring problem. This is a CMP gun. Jeff

Sounds a bit strange to me, maybe you have a lead ring built up and interfering with the nose of the bullet. Maybe give it a good scrubbing with a bronze brush.

But it wouldn't make much sense if oiling the bolt solved the problem.

Your right. I should of said that the bolt is full forward to the point of the handle being pulled down. Its at that point were you give it that extra push and drop the handle to arm the firing pin that it happens. If I remove the bolt and turn it upside down and clean the (not dirty) firing pin area with a cue tip and reoil it. It become smooth again. Jeff
