Testing 1/8 jig heads

[liftbite56]

I have 3 do it molds egg head, asprin, walleye head each weight about the same with -#1 hook in place . I use a bullet grain scale to get weights the same. 1/8 or .125. Should weight 54.6?? Forgot the exact ... Any way I've got them so close just had to cut the colars off to acheive the correct weight. I'm targeting the 15'-18' range. I'll be testing this weekend. If your long trolling what speed are you trolling 0.8-0.6? 1/8 oz to get down to those depths?
