I just bought a 6.5 PRC and was told by the company that I bought it from that that's what they recommend I use. I broke the barrel and when hunting second shot fired bullet stock would not fire try to eject. It could not eject it to save my life ended up, pounding the bolt. The case came out, but the head was stuck in the barrel. Luckily, there was an antenna on the car we had and I took it out. Didn't know what happened. Loaded the gun later in the day shot it and it worked fine. Just went hunting again. The other day fired my first shot bolted. My second stock put my safety on because it was stuck and it would not even take the safety off. Finally got it off. Same thing had to beat. The bolt shell came out and all the gunpowder and the bullet stuck in the problem this time is I was in the middle of a hunting trip and I did not have an antenna so I had to sit out the whole day of hunting because of it. I'm really trying to figure out what it is myself
