[QUOTE="TheDeicide, post: 1892726, member: 40022"] So this is my 28 Nosler with 155g CE MTH bullets in Peterson Brass with H1000 and Federal GM215 Primers. The spreads from 80.9 to 81.3 are unbelievable. The thing that has me puzzled being new to this, is the change between strings. I fired string 1 from low to high and then string 2 from high to low. I plan to load at 81.1 and play with depth or at least I hope to depending on what I can learn about that velocity jump. Also prior to this session I had fired 6 rounds after cleaning, so a semi dirty bore.
