Accuracy problem solved. I switched to a Minox 3x9 scope and hunting accuracy is back. Groups ran 2 1/4" using imr4064 and 154 sst reloads.
Accuracy improved with H380 powder and the new scope. 43 gr of h380 pushing 154 sst grouped 1.05 and 1.33. I accept that for this Mossberg timber hunting rifle
