Well, I seated the 165 sst's 5 thou further into the lands. No felt resistance closing the bolt. Group at 200m under 1moa with no flyers . No great pressure increase showing on primers. Load quite mild at 2750 fps with 57.1 gn 4350/ cci200 primers Norma brass. Might try for next node up next time. The identical load but with 165 SGk's same seating depth was slightly larger group and about 20fps less with great velocity variance so will try seating the SGk's a little further into the lands as well next time. All good.
