So i went out and shot @100 Yards. 3/4 in group and 1 in higher than my 130/NP using the exact same load just changed the COL. 130/NP @3.20 COL and 130/SST @3.25. I think i canlive with that???? Might try using H4831 i did't realize the Bullet length was that much different the SST was 1/4 longer (give or take) than the NP.
