Gunsmithing Ar.308 problems

Hi I recently picked up a 18 inch ballistic advantage Hanson barrel and I have had several issues with it feeding. After I installed the barrel with the gas block it came with, I would encounter two scenarios. The first being the gun would eject the round and lock the bolt back completely, not chambering a new round. The second problem I have is that the gun would eject the casing and rack a new round but it would jam. Upon examination, the jammed round would be slanted with the bullet pointed up toward the chamber ramp of the barrel and the bolt smashed into the side of the bullet, making a indent. I believe my gun is over gassed and is causing these problems. The casings eject to my 4 o'clock position. Some of the guys I asked said it might be a magazine issue because it won't feed right. But I use a 10 round P mag.

If my explanations are confusing, please reply so I can reiterate.

Thanks
