Hi ALL. New member here. I recently purchased a model 99 Savage in 300 sav. This was one that I've been wanting for a while. While I was tearing it down to give it a thorough cleaning and inspection I noticed that the rotory magazine was steel ( it"s magnetic) and not brass. This supersized me somewhat as I thought that the magazines were all brass. I researched it and was not able to find mention of a steel magazine. Can anybody shed some light on this? The serial no. is 683xxx which puts it being manufactured in 1953 Thanks
