[QUOTE="Reelamin, post: 3038576, member: 42157"] Your bolt or BCG has a male star pattern on the front. These are the bolt locking lugs with a squared front. The back of your barrel has the female “receiver” locking lugs with a smooth feed ramp area in the bottom center. The female side has taper, so they don’t usually create the sharp squared gouges in your case. When the bolt goes forward it picks up the base driving the case forward into the feed ramp. The case will go far enough forward the mag feed lips will release it to go inside bolt face and feed into chamber The bolt locks when it turns slightly locking it together. Look up bolt over riding and it will cover all the options on what causes it. Compare to what you have going on and it will start to make sense. [/QUOTE]
