Sounds like you have a primary extraction problem.
To see if this is your problem, put a shim, such as an old credit card between the rear baffle and the bolt handle where they are angled and should cam against each other. If this solves your problem, you either need a new bolt handle, or need to fix it by installing some sort of shim. Somewhere there is a link about drilling and installing a setscrew to act as a spacer.
Do a search for "primary extraction" and you will hopefully see that others have the same issue and some of the possible solutions.
