I recently purchased 2 RSM rifles in .416 Rigby.
Being somewhat familiar with the RSM, I have 8 in all three calibers, I am a little confused. My other rifles have much smaller diameter barrels. These two rifles also have different prefix serial numbers...750-00024 and 750-00030. The barrel taper starts much further down the barrel and the diameter is 1/10"" smaller. I also noticed that the front sight is slightly different. Comments?
