Practice mostly 5-50 yards.
But roving around the sand dunes and lupins at my local beach,Ill see a log two hundred yards away and give it a crack.
I live on the upper west coast of NZ,my local beach is 26 kms long an most of it is deserted for 6 months of the year.
I can do pretty much anything I like down there.
All this practice doesn't mean a great deal to me in a deer hunting situation,it's still a deer,I'll still be on edge to some extent,I'll still try to get as close as I can,,I'll still blow more stalks than I'm successfull on.
20 yards is a drop shot,30 I know I can do,,,10 would be much nicer.
