My suggestion, switch the level 10 back to a level 7 bolt. The level 10 requires more psi to fire which means the bolt is more then likely being reset faster/harder then the wave spring can hold. Also, if you dont have it already, you might try the short spring with the level 10 or turning the velocity down.

I have never tried a level 10 and pump mag together, but I belive that is the main problem.

If you are using level 10, try a different main spring. Personally a pump mag with level 10 is a PITA. I know a few people got it to work, but it's never been reliable for me.
