I went to the range and shot my 270 and it was .889 and i realized the other group was inaccurate.

Thanks for reposting- the math was bugging me. Still a great group. Your horizontal spread is likely just your heartbeat.

    What is the barrel length? I shoot a 24" barrel and I can't get the velocity from h1000, or rl25 that others on this forum have. I have better performance from 7828 in my rifle.

    slow down to rl25 or retumbo if you want to crack 3300 fps. rl22 and h1000 are known to top out at 3300 fps give or take with 140-150 grain pills in many stw's. My dad's been shooting a near max load with rl22 and a 140 sierra in his 7stw for years and it's not over 3350, I think a bit less.

    What can I expect from a 150 gr. Scirocco starting out at 3300 on a deer from my 7mmSTW?

    Those are bonded, so it should petal back, stay together and go through.

    If you are looking for something between 3300-3400, the better options would be RL 22, 7828 with the 140-145 bullet. With a 140 TSX, and 79.3 - RL22' I am getting 3389, in one gun, and 3367 with nosler CT in another. Either one of those two are great powders for that weight, and desired speed. The H1000 will get you there, npbut you will need to burn more, and the muzze blast will be furious.

    That's pretty good groups
    Barnes will be fine, Killed my first Elk with
    the first Barnes bullets in the early days,
    only bad thing about them was the copper
    fouling.
    My .338 will shoot half inch groups all day long
    And my Custom .358 STA , the best I have shot
    with it has been 3/8 of an inch.
    I ordered two Barrels today 7mm 5R twist rate
    of 1-8.75 and we will see how it does with the heavier
    bullet weights.
