Mulls. I use the RCBS adn it is not as accuarate as others. But then again it wlrks pretty well for pull tirggers up to about 5 lbs. Where it falters is at high set weights on releases. Btu I use mine to count empty hulls that I bag in a hundred per bag. Saves all that counting stuff.
Thanks Jack! I just got a great deal on a real nice AR-15 and installed a new Timney match 3# trigger.The stock trigger tripped at over 9#'s at my Gunsmiths when I picked it up and it still feels a little heavy and I don't have a trigger scale at home.
