Overall Observations:
- Nosler's as predicted were a tad faster probably due to a better BC but did not group better.
- I probably could have been allot more accurate on the powder loads but I was a tad tight on time to make make sure I cold get my spot at the range.
- I am sure if I had a higher power scope I could have grouped a bit better but I just wanted to get a stable replacement load for my daughters Service Rifle.
- I was surprised how dirty the 2520 was from sub 80 rounds.
- The last 25.25 load was exponentially more kickback than any of the previous loads
- There was no visible signs of any flat primers or case marking issues or overpressure signs
- I really did not feel like taking it past the 25.25 load.
- 24.60 felt the best in shooting
- Sierra's seems to be more consistent overall
- I ran out of time but I also wanted to shoot them against a 5 shot group of IMI Mod 1 and Black Hills Mod 1 (5.56) - I will in the next batch
