Thread: Improve accuracy ?

You haven't mentioned it and no one has asked but are you reloading for it?
If not, see if you can starting doing that and if you are maybe a different projectile or seating depth could improve your groups.

If you can find another stock for the rifle for cheap, you could use that for experimenting with, so try removing the pressure points the glass bedding it.
And if it all gets worse you still have your original stock.
