Back in the 70s, Hunter Safety courses taught the lightest a field trigger should be was 3lbs.
Lighter triggers are useful, or can be, on target guns and varmint rifles, but have no place in the big game fields, or stalking small game. The comment about gloves is very apt. Cold means gloves, and a very light trigger can be pulled by your glove before you even realize your finger is contacting the trigger.
I do like very light triggers, even under 1lb for some specific tasks, but not for general hunting. Its an accident waiting to happen.
