I'm running a 6.5-06ai I think its a 1:9 twist - the 140 AMAX & 140 Partitions are my go to pills. RL25 + Norma brass w 140AMAX gets me 2980fps and 1/2moa groups. Running RP brass (heavier) w same components the node is lower around 2930 fps. I have yet to try 143ELDx (for when I run out of the old AMAX's) but I'd think they'd be very similar as would the new 140 ELDMs.
