So I just had my custom Weatherby MK V chambered from 7WSM to 7 Rem mag. That being said, I am heading to Africa in 2 weeks. I never could get the short mag to feed in the long tapered magazine so I decided I didnt want any dangerous game stomping me down in the ground on a charge as I try to shoot my single shot at them!!! So sunday my smith went to work and we re-chambered to 7 rem mag. The rounds fed just fine. All I have to do now is get my OAL of the chamber. Well I didnt have a COAL gauge so I take a once fired piece of brass that has not been resized. I get a 168 Berger and set it in the neck. I put the round in my chamber and push the bolt forward. As you all know, this pushes the bullet into the neck giving me an OAL and gives me a good starting point to load my rounds. Well this was what I wanted to happen!!! When I pulled my bolt back my extractor claw broke off!!! It left the empty brass and bullet in the chamber and now im stuck with a broken bolt right before i leave for the hunt of a lifetime!!! So i get my cleaning rod out and send it down the muzzle to extract the brass. That worked to get my brass out. But Im still freakin out about my bolt being broken. So this morning I call the smith and got my part ordered. I got to thinking about it and am glad it happened now instead of when a jaguar or lion was bearing down on me. I guess I cant be too mad!
