I'm trying to get a good load with 130gr Partitions in my .270win. It's a Rem 700 adl. I used the ocw method and worked up from 54.9gr of H4831sc with WLR primers in new WW brass. I've attached a picture of my load data and the groups that I shot with each powder charge. I should mention that I regularly shoot one hole groups with this rifle using Hornady SSTs and even with different commercial rounds. I'm thinking that I need to go back and retest the powder charges that I used for sighters. Two of those shots were overlapping with one flyer that made for a 1.2" group which was the best of all, even though there was a huge spread in the three powder charges. What do y'all think? Do any of you shoot this load with a similar or matching rifle and would you expect one hole accuracy at 100yds with this bullet?
