No, don't dry fire it with the rifle assembled or you'll beat the hell out of your firing pin and pin hole in the bolt.
REMOVE the trigger group from the rifle, close the trigger guard on itself and dry fire JUST the trigger group. As Hungry likes to say, sit in front of a hockey game and do it over and over again for a whole game. It should smooth up substantially.
Whoops, I should have been clearer, that's what I meant. Thanks anyway!
