I have a stevens 200 in 22-250. I have been working on a load for it and I noticed everytime I fire the rifle seems to have a heavy hum. I can feel it as I hold the rifle as if there is a tuning fork in the butt stock. Any one else have this problem? Is it something to worry about? My accuracy and consistancy doesn't seem to suffer and I've checked all my bolts and screws.
