After learning how they were doing it, I made my own: sports bottle with exactly 4 lbs. of change in it, checked it with a very accurate digital postal scale, cross checked with a second scale. I used a bent heavy gauge wire for a hook, and then I could learn that my Lyman gauge was off by 2.1 oz @ 4 lbs.
Each gun therefore needed to read 4 lbs. 2.1 oz to just be exactly 4 lbs trigger pull, so I added 2 oz more to be even safer. Now each gun on the Lyman had to read 4 lbs, 4.1 oz OR MORE in order to pass.
My double check was the simple 4 lb weight/bent wire hook, each gun had to pass that test too. The guy in the armory (Lance, not Dwayne) kept rechecking each one, he seemed surprised they passed--but if I had trusted the Lyman, they would have failed!!!
The problem with only using a 4 lb weight to calibrate your triggers, is that it is a pass/no pass deal, you might make the trigger much too stiff, if you cannot tell what your adjustments are doing--it passes the weight test, but it might be much higher than you want.
