I'd go 140gr +. They maybe slower than 120gr but they will be better in wind, and wind is generally the problem at longer range especially if you have a good consistent load that doesn't have to much vertical dispersion. Just finished load development with my Tikka 6.5CM yesterday. Running 147gr ELD-M's loaded 15 thou off the lands (LTO = 2.310"), they just fit in the mag at that. According to my chrony they are running at 2,690fps (although it generally seems to read slow amd I prefer to use actual drop info to back calculate velocity) with an ES of 17 fps and SD of 6.7 fps. Lapua brass, CCI450 primers and Norma URP powder.
