    I am trying to consolidate my powder purchases a little. Does anyone have any load data for a 300 WSM 180gr bullet using H1000 or IMR 4064?

    I have only used H4350 and RL17 in my 300 WSM. I highly recommend RL17.

    I have tried RL15 & 4350 & RL22.the RL15 shot best groups using berger vld 168 but average was 2850fps

    What load do you use with Rl17?

    With RL17...

    168 TTSX's, 65.5 gr, 3071 fps
    180 E-Tips, 67.5 gr, 3193 fps
    210 Bergers, 65.5 gr, 2935 fps

    The 168 TSX's showed pressure signs a little sooner than I expected and did not achieve the velocity of the 180' E-Tips althought the 168's were lighter and had less bearing surface which I thought was very unusual.

    These were max loads in "my" rifle (Sako 85 Finnlight, 24 3/8 barrel) so if you try RL17 work up to these.

    +1 on RL 17 and H4350

    IMO forget h1000 and RL 22.

    Plus do not use magnum primers., stay with the standard primers

    With RL-17
    66.5 gr - 168gr Barnes TTSX - 3120 fps - .600" grp @ 100yds

    With RL-15
    61.5 gr - 165gr Accubond - 3210 fps - .75" grp @ 100yds, 1.7" at 200yds

    Both are max loads!

    Could not get accubonds to fly well with RL-17
