    Anyone shooting 180gr Berger's in their 7 STW. I have a 9x barrel, and thought I would try some. Berger website shows 9x will stabilize them. Anyone have any velocities out of their 26" barrel ?

    I shoot a wildcat just a bit larger in case capacity than the STW with a 9 twist barrel and the 180's. My velocities will be more than the STW, but they stabilize just fine.

    Hi Joel,
    Thanks for posting. Thought I would toy around alittle with the 180's and my 7STW.

    Trueblue,

    You should be just fun here, but Berger's recommendations are usually pretty good about what these bullets will or will not do in re stabilization. Give it a try, but I doubt you'll see any problems at all here.

    I don't have a STW but I have a 284 Win with a 1-9" twist 29.5" barrel and shoot the 180 Bergers at 2870 fps, they stabilize fine out to 1000yds, I shot a 6.1875" 5 shot group with it today in windy conditions.
    I think they will shoot just fine out of your STW.
    Regards,

    Great shooting Wayne.
    I think I can get 2950-3000fps with them in the STW. Could be optomistic. Will see.

    Update,
    Decided not to try the 180's. After running ballistic software the 180's under
    perform the 168gr.
    168gr Berger @ 3125FPS 20.25 MOA @ 1000yards w/ 1265# energy
    180gr Berger @ 2950FPS(est) 22.25 MOA @ 1000yds.w/1264# energy
