Depending on what model you get some of them go much less than 2.5 pounds. My last Accutrigger was set around 18 oz. They do take a little getting used to and they have some weird safety features that annoy the hell out of some people depending on their trigger technique. Personally, I love them for factory triggers and once you get used to them they are nice to shoot with.
I have one on my Savage 12 in 6.5-284Norma and like it alot. Mine is adjusted down to 2.5 lbs with no problems or glitches. My other Savage 112 wears a Rifle Basix, my Sendero's factory trigger has been cleaned and tuned, as has my Winchester M70 HVB's factory trigger. All tuned down to about 2.5 lbs and I can't tell alot of differnce in the four.
Never owned a Jewell but IMO the Accu-Trigger is a helluva' sight better than the old Savage "adjustable" factory. Enjoy. JohnnyK.
Putting to much pressure on the side of the centre leaf in my case is not what causing my target accutriger to lock-up it just putting pressure on it will cause engagement of the safety mechanism. How frustrating can it be, when you ready to take a long shot and that trigger locks on you and you have to cycle action to unlock it. Another thing I noticed, after I adjust it to 2lbs last fall at this setting I had no issues with safety lock-ups, but last month while I was at the range it start to jam again and I had to do field repair on it, which required taking action out of the stock and without torque wrench on hand I had some fun getting it back to where it was. In my opinion if you got hunting accutriger, it should be OK, on the other hand their target accutriger not worth it. Also on my 111 long action build I replaced its heavy hunting trigger with Riflebasix trigger, and I absolutely love it.
Big Creek Regulator, be careful with what you have now, since accutriger have tendency to fire while you cycling its action, in my case it would snap on bolt close, but since middle leaf in my case is in place it wouldn't fire, but without one you'll get slam-fire.
