It really depends on how light of a trigger you plan on shooting. If you are used to factory triggers and their 5lb plus pull weight, then it may not do you much good to get a jewel yet. Reasoning is that if you're used to 5#, then 2.5# will seem very light indeed. Most remingtons that I've messed with will go down to 2.5#'s safely.
The Jewel comes in when you want a trigger lighter than 2.5#. They will go down to a few ounces and still remain safe. One other thing you get with a Jewel is they are super crisp. Sometimes in order to get a factory trigger really crisp (no creep, meaning minimal sear engagement), it borders on unsafe.
The rifle shouldn't fire when we slam the bolt forward, close the bolt very quickly, tap the bolt shroud with a dowel, activate/de-activate the safety, slam the butt against the ground, or push on the side of the trigger. Pull weight should remain constant and not change. The Jewel triggers will pass these tests and give a light, crisp, consistant pull too.
After a while, you'll get used to 2.5# and find that you're still sometimes pulling the rifle off your intended target in order to break the trigger. This depends on target size/distance, shooting position/steadiness and optical power however. You may never notice it on big game with 9X optics and a casual field rest. But you will notice it on prarie dogs from the bipod with 24X optics. Best scenario IMO is to set all your rifles at the same pull weight, or as near as possible. What ever that comfortable, safe pull weight point is for you.
"Most people" seem to think that 2-3 lbs is plenty light and borderline "unsafe" on a hunting rifle. I think it's a matter of what you're used to using and your personal practices of gun handling and trigger finger control that determine if it's safe or not. If I get used to a 3lb trigger and then go and shoot a 1 lb trigger, sure; it's gonna go off before I expect it to. On the other hand when I am used to a 1 lb trigger, a 3 lb trigger feels like the safety is on!
If we don't touch the trigger until we're ready to fire, then there is nothing wrong with a trigger lighter than 2lbs IMO, and that's a strong opinion because I've pretty much used nothing but 1.5 lb or lighter triggers for nearly 20 years now. Granted, Obviously we don't want to be dropping a rifle that's cocked and locked that has a really light trigger pull, but when I am actually ready to fire; the odds of dropping a rifle are way less than winning a lottery. I am already as steady and supported as I can be, and the rifle is already pointed at the target before I even touch the trigger. I've also made it a habit of removing any gloves before I shoot.
IMO, It would be more "unsafe" to have a 3lb trigger that we shoot often, and switch to a 1lb occasionally, then it is to just stick with 1lb all the way.
