Everyone is different. Hunting triggers are usually adjustable from 3-6lb. Some lower.
I like 1 1/2. I use Weatherby so the safety on the bolt is not effected by light trigger settings. I never trust a safety anyway.
For non hunting I go down as far as a few grams on my Conjar triggers.
There is no right or wrong, it's what you want.
All of my hunting rigs have triggers that are adjusted or tuned to less than 15oz, a couple are 7oz and 9 oz. Thats just how I roll.
My BR rigs are closser to 4 oz.
THE most important thing is that the trigger break at a CONSISTENT pull force.
