Nice deer, but it doesn't mean a thing about your trigger being properly adjusted. A good shot could have done the same with a 10-lb trigger.
Safety is foremost, and it varies for each rifle. The weight of the trigger that is good for one shooter with very sensitive touch will not work for some other ham-handed shooter. It's like saying everyone should drive X miles per hour. You can't make that generalization. But it is a safe bet most people have no business driving 100 mph anytime, just like having a 2-lb trigger on a hunting rifle.
