i want to have one built on a sako 75 action,with a 24 inch barrel i want to know what twist barrel to put on it.

should be shoot, i've been accused of alot of things in my life...being smart aint one of them!!

Let your gunsmith be your guide.....or call Chris at Pac-Nor and ask him. Easy to talk to and very reasonable + he can true-up your action and rebarrel it at a very nice price.....good work too.

Chris;
I have one, and have yet to draw blood with it, but I really like it! I'm getting sub moa at 100 yards and just starting to load for it and so far I've pushed a 140 (My favorite) grain Sierra BT 3200fps! Go for it I think you'll be pleased.

The standard twist for the .270 is a 1-10 especeally if you are going to shoot 150 gr or heavier bullets. I have seen some 270 with a 1-12
but they shot nothing heavier than 130 gr bullets and used 26-28' barrels. I would stay with the 1-10 if it were mine you can't go wrong with that.
