I've also had a few (4) light strikes on Geco solid slug, but apparently they're notorious for having hard primers (It was news to me). I got a fail to eject and a fail to feed in this video at 1:43 and 2:25 (respectively) both caused by the magazine (the spring was too strong and caused friction on the bolt), the problem at 1:56 was the hard primer. All of the malfunctions in this video (apart from the major one on the 'blooper reel' which was caused by the brass separating from the case) were with the Geco slug ammo, and the first stages of the day.
I've got another Lv3 comp this Saturday that i'll be using my BR99 for so i'll see how i get on. More shooting is needed before i'd recommend one for serious PSG use
