    Hello, please help me decide on the best twist rate for remington 700 7mm mag. Would like to be able to shoot 140 thru 168 grain bullet.

    Just because someone else's rifle will shoot good, doesn't mean yours will. And just because you use certain products doesn't mean you're gonna be able to shoot ultra-tight groups, like someone else can. Not everyone is capable of doing such. Some folks flinch, some folks shake, & some folks get target-panic. You could put his rifle in the hands of 2 other guys, and none of the 3 will be able to duplicate what any of the other ones did.

    Just food for thought.

    And no, 1:9 is tight enough for even the 180gr Bergers... So yes, 1:9 is still what I recommend.

    According to Berger, a 9" twist is good enough for the 180's :)

    Mark, I know...I said it was. Re-read my post. I was saying "No" to his question about going with a 1:8 twist. LOL But I can see I should have specified on that a little bit more.

    I shoot 180's out of a 9.25" twist, and it stacks them...But my gun is also apparantly a freak of nature. So all my replacement 7mm barrels will be 1:9.

    You can answer these questions with a little research on your own. A good way to learn. The best source to get twist information is from the manufacturer. You can check thier web site or call them if not posted online. You can also use that twist/stability calculator I linked in your other thread.

    If your max is 168 grain. I'd go 1/9.5, but if you think you may ever go to the 180 class bullet. 1/9.

    I ordered my 7mm barrel 3 months ago, I am similar to you, think I will shoot max 160, 162 or 168gr bullets. BUT, I ordered a 1/9 just for the option of heavier bullets.
    BTW, will be a 7 SAUM, 26"
