The first time firing, the case didn't fully eject. Second time firing the bolt locked up due to forward assist locking bolt closed. The forward assist was bent due to being too long and jammed from the recoil. I ordered a new forward assist to correct the bolt being locked up, but it is still a hit or miss if the cases eject or not. I suspect the extractor being the issue with being a rebated rimmed cartridge with a standard lenghth extractor. Further investigation is needed to correct the problems.
