Bob,
I use my Bird 43 terminated with a dummy load when the power level I want to measure will give a good meter deflection with the slugs I have available.
Like Don, I find the voltage method handy when working with QRP rigs, since they barely deflect the Bird with any slug I have. I use an ME-26D/U Vacuum Tube Voltmeter, the military version of the HP-410B, to measure the RF voltage across an accurate 50 ohm dummy load and do the math.
With my K line gear, I use the meter in my KPA500 on a daily basis and give it an occasional double check with the Bird to make sure both are working as intended.

A comment here, has anyone thought to use a Bird 43P with a 100 watt HF slug? Or maybe a TelePost LP-100a? Both are equally good regarding power measurements but only when the load is 50 ohms resistive.
