I just bought my first Savage rifle. Its a model 11/111 trophy hunter XP in 30-06. I am having exactly the same problem. It randomly wont feed rounds. If I push up on the magazine from underneath it will work every time. It's as if the magazine is not seating well. The range officer where I went to test the rifle owns several Savage rifles and was shocked by the malfunctions. He looked it over and and advised me to contact Savage. After speaking with their customer service they are sending me a new magazine. If that doesn't fix the issue it will be going back as well
