4 to 4.5 lbs on the front and 6 lbs on the rear is what I believe most manufactures strived to get. I find that combo just about right. I have a Fox A-grade that has a great front trigger, set at about 4.5 lbs....and the back trigger breaks at over 9.5 lbs!!! Terrible and I cant hit shinola when I "try" to shoot the left barrel...I will soon have the back trigger set for a crisp pull of 6 lbs.
