View Full Version : Dry fire deviation

December 29, 2016, 09:56
I have an FNH SPR rifle with an SWFA 5-20x SS scope mounted in Nightforce steel rings. I have noticed that when dry firing, the reticle will move downward on the target roughly .5 MOA upon breaking the trigger. Live fire results are vertical stringing usually all rounds touching.
What could cause this?

Is the action tight in the stock ?

I checked all mounting bolts as well as rifle stock torques. Today I removed the optic and rezeroed it. So now the testing begins.
