    I finaly picked up my 7mm stw. I bought a rem. 700 bdl with a 26 in barrel. 1 in 9" twist.
    I have a box of Berger VLD 168grn. and Nossler accubond 160grn.
    The powder I selected was RL-22.
    I haven't had time to make any loads yet, but just wanted to get confermation I was on the right track. I don't have a lot of reloading experience.
    Is there another powder or bullet anyone would suggest? Retumbo?
    Thanks for the help.

    Retumbo and H1000 are both good choices.

    IMR 7828 was developed for the 7mm STW and would be another good powder to try.

    Powder that will give you near 100% case density at max pressure has been most effective on
    my STWs.

    RE22 is on the fast side for 160 grain and heavier bullets out of mine. It will shoot well just the slower burning ones do better for me.

    I shoot 77.0grs of Reloader-22 with a 160gr Accubond.I could possibly go up a grain to a grain and a half more,but I'm getting great groups with it in my Sendero,so I left it at that.I was also getting just under 3200fps.

    I loaded for three different STWs'.

    RL-22 and IMR7878 were my two favirites.

    RL22 is really good with the 140 grain bullets. The heavier bullets will bring alot higher performance. The 180 Berger and Retumbo is a great combination.

    Another vote for 7828. I load it in two STW's and excellent accuracy and velocity in both. Great cartridge.

    I shoot a 24" barreled STW 1-9.25 twist and here is what I load:

    H1000 140 Gr. TTSX - HbN coated 3450 fps
    Retumbo 180 Berger VLD 3000 fps

    Both go 1/2 moa

    I have had great luck with Retumbo and both the 160gr Accubond and the Berger 168gr VLD. The Berger shoots .75 moa at 3200 fps in a Sendero barrel.

    The nice thing about H1000 and retumbo is they are both in the extreme line of powders. Now I know out of a regular 7MM I use to get great acuracy with IMR 4831, but am not sure how temp sensitive it is????
