Im shooting the 150 partition with 60.5 gr of R26 from a 23 in barrel and get 3087 fps groups average .5 moa at 100yds and 3.5 at 450yds.
I can go to 61.5 gr at over 3100 fps but the group opens to .9 but is hard on brass.
Primer used Fed 210 case neck down 30/06 Lapua.
Optic Trade from Slovina awesome to deal with I bought 4 scopes 1 range finder and binos all high end stuff S&B Zeiss Leica no tax big discount and you get your shipments in 3 days yes 3 days ups express saver.
Hope this helps
