I have a savage 116 that was chambered in 300wsm, it down right hurts to shoot. so I put a 300 blackout barrel on it. now my problem is that a have a bolt from a stevens 200 that was .223, I set my barrel up with go no go gauges and it seemed to be ok. But I chambered a dummy round and the bolt wont pull the round out.(I already pulled the extractor from the controlled feed set up out, so that's not it) the bolt bodies for the 300wsm and the 223 are the same length but the 223 head is a bit shorter. what should I do? any ideas would be greatly appreciated.
