I've never had an issue with the accutrigger. It's nowhere near as nice as say a browning X-bolt, or other high end rifles, but for what it is it functions fine for me. It seems to be that few people think it's amazing, the majority of people think it's pretty good and some seem to hate it.
The only things I have heard you should watch for are as someone said above, if you put side pressure on while pulling the trigger it can cause issues, and I have heard if you have thick gloves and adjust the pull way down you can have your glove press the trigger before the middle safety is fully pulled back and it will trip the safety on it and you'll have to lift the bolt handle to reset it. I haven't personally had either of these happen to me, but I heard it on the internet.
