Not sure if this is right place for this or not.......

Something I have noticed over the last couple of years is I have started to developed a flench. I have had the same .270 for the last 12 years and don't know why this has started? I have never had this problem before, and don't want to take a chance when taking a shot. Does anyone know how to stop this or know what I can do to reduce this?

Any advice would be appreciated.
