    Great info Iron Worker! It appears that your velocities with the 22-250 basically mirrors Wincheters info. That is quick for a 55gr pill.

    Iron Worker, is there any chance you'll be trying some Nosler 70gr Ballistic Tips in your 6CM with the StaBall 6.5 powder???

    Johnnys reloading bench on YouTube did a temp stability test, for this powder. It still is not as good as i would think it would be for a powder that’s advertised as being temp stabile

    No . My bbl is an 8"twist, also the powder is best with heavier bullets . I'd suggest trying W-W 760 for 70gr bullets.

    Mine 6CM build will be using a 20in 9tw Proof barrel and those 70gr BT's with RL16 will probably be what I try first, but I think that new StaBall 6.5 will work well with pretty much all of the different bullet weights in the Creedmoor size cases. Being that it's a ball powder, running out of room in the case and not being able to get enough in there, shouldn't be a problem like some of the other stick powders.
