I short gate to drain with tweezers.Black probe source, red drain. Reads open.Black probe source, red gate and then back to drain. It reads voltage drop. Same precedure on both mosfets. Except each one reads different voltage drop.
Gate voltage threshold varies a lot between invidual mosfets resulting in one of them to turn on more completely than on than the other.
Try shorting the fet out completely (all pins shorted to each other) then just read from source to drain.
