I went to try out my 858 last week and I had no issues overall. However, when I load a new mag and pull the bolt, if I help the bolt move a little or pull like a pussy, the round jam at an angle in the chamber, according to my flawless math I would say 26 degree up. I gotta remove the mag and wiggle or give a couple of light taps on the bolt to force it in. I'm not too happy to see a pointy round getting stuck right in the bore, even less to think the rounds violently chamber themselves when I shoot and must be scratching the #### out of my barrel if something is wrong.
