Ran 34 rounds with the EC Tuner Break on this morning. Same load as above jumping .030" off x1 fireformed brass.
POI shifted a little, but I also reset my scope on the rail going back one slot for better eye relief. Was only a few inches off. Barrel was squeaky clean and today it took 4 rounds to get back up to speed. Speeds were about 12 FPS slower than last weekend with about 25° difference. N570 isn't the most stable. I really wished Retumbo would have worked.
Position zero wound up being the best over all. Had two rounds touching. Position #4 was close, but everything else was off and I wasn't happy at all with the results. Went back to position zero and locked in it. Last 5 shots were to get a true 100 zero after the barrel had cooled. Looked up at the Garmin and was pretty damn pumped.
