Having pretty good results with the 90gr ELDx in 243 win too. Sako A7 with hi tec stock. 44gr of 2209 = 3160 fps and 0.4 MOA groups. COAL at 2.766 which is around 20 thou off the lands.Good to see they perform in the field too.
That is seated out very far. Was running 85gr Sierra at 2.650 and having real problems but wound back to 2.620 and back in in the honey.Simply not enough neck stability and cases not trimmed.
