Since you own the Lapua, by all means use it. I wasent aware you had that. Lots of us can lay down prone with a bipod and
amaze ourselves shooting at various type targets at considerable distances. But the location we shoot from is selected, the target location
is selected, and even the weather conditions we shoot in are selected. None of that is apt to be true when hunting.
So cheat whenever its possible to improve your performance. Pride should take a back seat when shooting at live targets.
The shooting shack is a great idea if you can build one where you hunt. It will also allow for hunting in poor weather conditions
by keeping the equiptment dry. Definatly build a shooting bench or incorporate one into the design of the shack.
Consider having the front lift up and remain up with some type of a prop arraingment. Except for the bottom part which could serve
as the bench. Windows fog up unless their insulated glass. The propped section also serves now as a roof to help keep rain further away
from you and the equiptment. Glasses, glasses, glasses, big tripod mounted glasses, are your most important item of equiptment.
Without them your driving without headlights. A spotting scope is simply ok, and that includes $2000 ones. Close one eye and walk around for an hour
to get the (picture). I could email you some pictures of what im talking about.
