Jeeze! Where have you all been the last twenty years, in a cave?
I know it is a little bit different with me, but I learned a long time ago I was missing so many opportunities by trying to find a knee, lie down, a tree/bush whatever. Then I made up a pair of cheap sticks out of the cheap plastic coated ally garden stakes and boom!
Instantly revolutionised my work.
I never, and I mean pretty much never take a shot other than off sticks whether it be sub 12 for rat or .308 for deer.
