    I saw very good accuracy. Half MOA out to 900 yds. My barrel is slow, but I ran them at 2985 fps. My 300 Win Mag is a actually faster at 3000 fps with the 215. Load both rifles with Fed GM 215 match and H1000. RUM barrel is toast so switching it to a Edge this winter.

    Excellent accuracy, 26'' Proof with a 1 in 9.4 twist. 93 grains of N570. I can't remember off the top of my head how far off the lands they are. One hole groups are not uncommon.

    Low to mid 3100's would be pretty normal from 26-28" barrels using powders like H1000, Reloder26, Reloder33 etc.

    3050's for me, with 89.5 Retumbo/Norma brass/CCI-250. Rem 700 LRH stainless 26". It's a nice accuracy node.
    Just started experimenting with RL26, so far so good!

    All three of my Rum's shoot them around MOA or slightly better at around 3100fps.

    I won't shoot them at game but they are hell on varmints and predators as far as you can reach out.
