Thanks guys, I completely agree that a smooth trigger pull trumps a light one, but a lighter pull is preferable for accurate shooting compared to a heavy one...provided the firearm remain accurate and it's light within reason for it's intended purpose. A hunting rifle's pull shouldn't be less that 2 lbs., really.
The Wolff kit comes with a lighter trigger return spring, which is great, and then a 9, 10, and 12 lb. spring. After I shim and polish the moving parts, I'll try the 9lb. spring with Federal/American Eagle ammo, and see if it's consistently reliable. If it suffers from light strikes, even with the Federal primers that are supposed to be easier to fire than other makes, then I'll switch to the 10 lb. spring. I'll test it again, and if that is the perfect hammer spring weight then I'll go with it. It's purpose is target shooting, and even in that primary role it needs to be reliable. Stuart, thanks for the tip.
