    SAAMI specs for the 270 Win is a 1 in 10 twist. Sako would have made their barrels to that spec or the metric equivalent. If you have the rifle in hand, just measure it & confirm? Cleaning rod, tight fitting patch, pencil, & a measuring tape are all you need.

    You've had the rifle since 1985. So why, suddenly do you "Need to find out barrel twist"?

    Methinks it has something to do with the current fashion of blaming/crediting accuracy or accuracy problems primarily on twist rate, a fashion which, like others before it, will eventually fade.

    I agree with stonecreek. This issue of fast twist has gotten out of hand. If you just want to find out what the twist rate is, it is as easy as paul says.

    I have killed lots of game and tens of thousands of varmints with a standard bullet in a factory Sako barrel.

    My son and I are starting to reload in 270 and he ask what the twist was.

    Maybe someone is making a longer bullet, but a 150 grain spitzer boattail would be about the longest commonly available bullet for the .270. I've never see a Sako which wouldn't stabilize such a bullet.

    Hello Steve,

    Am I right in saying that the .270 Win. cartridge [ Loaded } is longer than the .30 06 Springfield. I have a 1957 .270 Win. Brno ZG 47. Highly prized!

    SAAMI OAL is 3.340" for both the 270 & the 30-06. A reloader can set his OAL for optimum performance & to accommodate different bullets, so length may vary in that regard.
