Dime and washer drills... old Army thing. Place the front of the gun on a rest, and have someone (shooting buddy in Army Basic) balance a dime or washer on the barrel. Pull the trigger. If the dime or washer falls off, you fail. Practice until you can pull the trigger smoothly enough that the dime or washer doesn't fall off the barrel. Troops train all the time, with the heavy-ass trigger pull of a military issued weapon, to accomplish that task. They pass. They must, continually, pass, before shooting BRM... It works.
