I replaced two or three 10rd magazines for the same reason. I have 17HMR. Try to load 7-8 rounds and see if the rifle cycle them or not. Sometimes a magazine works ok if it is not loaded completely. You can also try to bend the magazine lips with plyers to adjust the position of the round. I found Savage 10rd magazines commonly have issues and, to be honest, I prefer to use 5rd.
