I bought a savage model 11 in 300 wsm and it had the worst machined chamber that I have ever seen! Looked like they used a chain saw to machine it! Sent it back to savage and they "Honed" it and it tested fine. I've fired a box through it and the first 3 rounds were fine. After that they started to be hard to extract again. Every piece of brass coming out has rings on it where the brass is expanding into the marks in the chamber and getting tight! Now I have to send it back again for the same issue........ Anyone else had any similar experience?
