I have been doing load development with my Grendel for a couple weekends now with no good and repeatable results with extreme spreads or groups. Last night I noticed that my clamp on gas block was lightly contacting the guard, I knew it was really close when I built it but I thought I would be safe. I changed it out with a set screw type. Question is how bad could it affect the groups on paper It was barely touching. What have you guys experienced. Thanks
