You have a primary extraction issue. Test it by inserting a .010 or .015 feeler gauge between the action and the rear baffle when you have the issue. It should engage the ramp and easily pull the case out. To fix you will need to close the gap between the rear baffle and the action. You can A; fix the bolt body, B; try the set screw method or C; try different bolt handles till it works. A or b is your best bet unless you have/find a SSS handle.
