[QUOTE="Starlite, post: 1857660, member: 112246"] Sorry for the horrible writing. Curse of the medical profession. if you can see the highlighted areas. 40.0 gr gave the best numbers and the best group of .420” 41.0 gr was next best numbers but 40.5gr had a better group. I didn’t exclude any shot as a flyer.the 143 Once this Covid is out of my area and our club opens again I’ll continue the testing as the COL was quite long with ~10thou jump. In the 127 Barnes ladder testing that same day. CBTO 2.1285 and COL of 2.7200. Fire from my Sako finnlight (20”SS Barrel). 43.6-43.8gr (~2700FPS) is the sweet spot. I’ll be testing that in the future too. For completeness here is some VV N-160/147ELDm. Not happy with the results but I’m sure the velocity and seating depth. MTF on that one too. THE 143 ELDX didn’t group well during ladder testing but did have a good flat curve so that will need a 3 round .5gr testing done to fine a best spot to start playing with COL and fine tuning the power.
