RE: Home made shooting sticks
I have always used a forked stick like you use to hold your fishin rod.cut to desireable length(I like waste high) helps in moving briars and the single leg can find a resting place no matter what.
Another thing I have used is two tobacco housingsticks.
measure 6" or so down each stick and drill hole.
wrap each stick in camo tape or felt.
secure the two sticks with a small bolt/washers/nut leaving just tight enough to barely move.
if you cant find housing sticks anystraight wood of equeal lengthwill work
