I fired 150 rounds through it today using Eley Benchrest precision. Now it has 200 total rounds through it. The last fired case still goes partially back into the magazine upon extraction. I thought by now all the issues would have been addressed and corrected. This happens about 90% of the time and with all 4 magazines I tried. Don't know if it is worth sending back or not, I still haven't decided. Bolt operation is not smooth as I am used to. Good trigger.
