Alright...I started working on figuring out this cold bore. Last night I left the rifle sitting on the table. I had a theory that standing it up in the safe was dropping all the residue to the chamber and causing cold bore shift. That however is not the case as this is the first target shot this morning.
So next I fully cleaned the suppressor. It has very few rounds through it and I didn't think this was it...but I don't want to leave anything to chance. However...this is the group after cleaning the suppressor. It still has an almost identical cold bore shot.
So then I thoroughly cleaned the barrel. Obviously the barrel needs a little seasoning before I can tell anything, so I shot three 5 shot groups. Cleaning the barrel caused a POI shift up 0.4 mils. That is much more than I would have thought. I have probably 1000 rounds on the barrel since last cleaning.
First 5 shot group. first shot is in the dot. Second shot is the middle one. next three in the same hole.
Next two five shot groups with a .4 mil adjustment to the scope between them
Next step is to let the rifle sit for a few hours and then shoot it again. Hopefully the cold bore poi shift will be eliminated.
