My 700 benchrest setup has a 1.5 oz trigger. You look at it and it goes off. It's not at all ok for anything but bench duty and your hand doesn't touch the rifle unless your'e behind the scope and on target. Honestly, this is probably overkill unless you're talking free recoil. I have let round go sooner than I wanted to with this trigger. Not negligent discharges, but while on target - just timed poorly because it's so sensitive. I would not even think about cocking this rifle until it was on target. It has no safety, because it would be insane to use the rifle in a situation in which a safety would be necessary.
My Barnard F class rig is set at about 8 oz. It's fine. For F class. I have no fear of setting it off accidentally in that setting. It's perfect for a long range target rifle.
My high power service rifle is set at 4.5 pounds per the NRA rules. It's a bit heavy for accuracy.
My field rifles are set in the 2-2.5 pound range. It's light enough to not add too much strain to the pull, and heavy enough to be safe.
I find that above 3 pounds it takes more work to exercise good trigger control. It can be done, but it requires more mental effort. Below 10-12 ounces, and the trigger pull becomes more like a thought than a physical action, which is what I want in a target gun.
