Yes I am contemplating doing the same BUT with a smaller auger , I find the 2 inch to be a bit much for my Dewalt , I would like to have a hammer drill , perhaps that would help some ? Now I use a one inch . Problem with us nobodies here in the upper 48
Is we have hard ground in a hurry , so any dirt holing has to be done early ! After the ground freezes it becomes a real task to set more than a few in a day . So my plan will be dirt holes early and then go to snaring . There is nothing like seeing the bounce from a distance when you get lucky at a dirt hole!
I used ant hill dirt that i had dried and kept in a five gallon pail . I have not tried calcium chloride yet .
