Been a while so i figure i do a little update.
Grabbed a satellite pic of my friends place, entered APPROX location of current targets as a number ( distance to it )
93 M is just over 100 yards.
We use a Leopold range finder and range back towards the big shed surface when we put up new stuff to shoot at.
Also highlighted the #2 place to shoot from if we get many visitors eager to get on the trigger, you can still get +100 yards from here.
But in general nothing put up here to shoot at, but that is a small problem.
There also is the old shot shed, granted you can see it from the new shed, but you will have to shoot thru a corrugated metal plate to get so someone there.
This can be bulletproofed if need be, just not by me, i have build the shed at my own cost and sweat of my brow, friend with arthritis helped as little as possible, and i am also going to be the one paying for the insulation and putting it up.
And i am on a pension, so not a high roller even by Danish miniput standards.
