With a Ruger, they calculate how much "interference" fit they need to torque the barrel so the front sight (which is already installed on the barrel) is rotated up to 12:00 when it reaches the specified torque.
If the gun shoots to the left, they torque the barrel some more so it moves the sight blade to the left, this makes the barrel point more to the right. Here is where it gets thread choked.
You really don't need to worry about thread choke in a .357 because the barrel stub (the threaded portion of the barrel that screws into the frame) is much thicker than a 44 or 45 caliber barrel.
45 Colt barrels are the worst ones for thread choke because the barrel walls at the threaded stub are thinner than any other caliber they produce on a single action frame and torquing the barrel distorts the inner bore easier, creating choke as they tighten.

Got a .22 .30 .32 .357 .38 .40 .41 .44 .45 .480 or .500 S&W cylinder that needs throats honed? 9mm, 10mm/40S&W, 45 ACP pistol barrel that won't "plunk" your handloads? 480 Ruger or 475 Linebaugh cylinder that needs the "step" reamed to 6° 30min chamfer?
