    Might be a bit slow for that bullet weight.

    I was thinking of trying H4831 as next step.
    In a perfect world I would be trying RL19 but this is rare in NZ.

    I can get Vihtavouri powders but can't find any data for STW.

    Why not try the 140 grain Berger? You can get it over 3500 fps and the BC will help it past a couple hundred yards.

    Thanks for the information I didn't know Berger made a 140grn for the 7mm. I will investigate availabillity.:)

    The reason I am trying a 120 Barnes load is I have found the Nosler 140 grn BT quite explosive on the Chamois we have in this country.
    Nice neat hole on entry and a fist sized hole on exit. They tend not to run to far though.
    I have had better results with the 140 Accubond but thought I would try the Barnes, (as they are quite often raved about) and go to a lighter bullet.

    Using 87.6-87.8 grns H1000 (ADI AR2217) I have achieved groups of 18-20mm(3 shots) @ 100m using Remington brass,CCI 250 primers.

    I have had keyhole groups with both the Noslers using the same but with 83.5grns of H1000.

    I am yet to chrony these loads as I do not own one and usually load for most accurate load.

    I have found I can get hold of RE22 and I looking at trying some of this over a chrony of a friend along with my existing loads.

    Hard to beat the H-1000 in the STW, I run 140's to 3550 in my bansner UR-1 with 86 gr of it.

    I know H1000 is great with bullets 160grn and above but alot of the reloading manuals quote other powders such as H4831,Reloader 19/22 etc with the lighter bullets.
    Have you found H1000 the best across your loads or is another powder more suitable with the lighter bullets?

    never shot anything lighter than 140's in mine. I tried re22, H4831, IMR 4831 and couldn't come close to matching the velocities I got from H-1000, the only other bullet I've shot in that rifle is the 160 accubond, running it with WC872. tried a few 140 original x-bullets but they didn't shoot well at all.

    jesse71,
    This combo to me is a total mis-match ( like Ellen DeGenerate getting married to her girlfriend). For a 7STW you should consider mabey a 160grain Accubond or a Berger168gr-180gr VLD and leave the 120gr copper foulers to the 7mm-08 crowd.

    Cheers for all the input gentlemen.:)
    I think I will stick with H1000 and the Accubonds.
    Some chrony time is in order I feel.

    Accubonds or Scirrocos are great too.

    Thanks.
    Scirrocos are a quite expensive down here and are not readily available.

    Has anyone tried Noslers ETip?

    I suspect they are just trying to compete with the copper club?
