A friend of mine tim, called me sunday night to tell me about a with a pro-hunter his buddy bought when they got back to the USA after being oversea's for a year (both of them are in the Air Force). They went to the range, his buddy put 1 round down the barrel and handed him the rifle with a case stuck in the chamber, and it did it every time they shot it. After getting the cases out they noticed the cases were slightly egg shaped. I guess when it comes back from TC it's going down the road.
