Pepemarine, Remington (http://www.remington.com/firearms/centerfire/fi_7awrmag.htm) lists the rate of twist for the 7mm SA UM caliber at 1:9.25". Hope this helps!

Pepe, the best twist rate always depends on the length of bullet you intend to use. In the 7mm 1-11" is best for bullets up to 140gr weight and 1-9" for heavier ones. The heavier a bullet is in a certain caliber the longer it will be. George
