I'd do it with a McMillan, a good synthetic is gonna be less of a problem. Make sure it's bedded so it always returns the same.
Doing an exact torque every time can't hurt, but my hand torque wrenchanometer has worked well.
Ain't nothing to fire a round or 3 when you get to where you are going.
Screw all that single shot crap, pull the stock off a bolt action and have at it.
