I have an update after shooting out to 500 yards last weekend. I shot two 3 shot groups at 100 yards with 0.55 and 0.6 MOA. But I also shot two 5 shot groups that exhibit the problem I am trying to fix. The first group had first shot flyer (and I don't think it was cold bore) and the other 4 very tight (0.6 MOA) dead center on tiny target with a total of 0.9 MOA all together. I then had another 5 shot group with 3 shots tight and 2 shots tight but in different spots spreading to another slightly sub MOA group. When going out to distance (500 yards) I was unable to hit 4 inch center target after 5 tries. I also had some really horrible flyers when shooting at 450 yards but realized it was due to bent rail that was connected to my bipod as a result of me overloading bipod trying to steady reticle. I was extremely uncomfortable and I am placing blame on the inability to get comfortable as the most likely cause of my inconsistencies with the Grendel. I bought a higher mount to try out since I have a very long face and really was having to twist my neck to get clear reticle view. Let me try out new mount as see how that goes.
I was shooting great with my 243 and 6.5 Creedmoor rifles which are very comfortable and getting very tight groups at 100 yards and dead center bullseyes out to 500 yards (see video). So, I have the ability as a shooter to shoot straight and steady. Let me try to mount and report back.
But it seems pretty certain the problem is not due to a gigantic burr in the barrel and that was just the gas port.
Here's video of target I as shooting at out at distance. Grendel was disappointing but this is video of 6.5 C at 444 yards and followed by nearly identical placement on next shot at 500 yards. These were both first shots at that distance which is what I'm trying to perfect with all my long distance guns - to be able to go out to distance and know exact scope settings/hold overs to hit dead center first try. Making progress but still have a ways to go.
