After getting the suggestion from Ry I have been exploring the possibility of doing a 1000 yard Boomershoot.

I did a few calculations with Modern Ballistics last night to see what would happen if people just overshot the target area. My cousin's house is a mile away and pretty close to directly behind the proposed target area. The house is out of sight and I suspected the shots would over shoot the house and land in the fields behind his house. It turns out the answer depends on the caliber being shot:

• A 7.62 x 39 (yeah right!) bullet would land in the field several hundred yards in front of the house.
• A .50 BMG bullet would overshoot the house by a few feet.
• A .300 Win Mag shooting Blackhills Match ammo with a 15 MPH wind from the West would put a bullet through his living room window.

I haven't checked with my cousin yet but I suspect the safety margins are not acceptable.

It is very unlikely there be 1000 yard shooting at Boomershoot 2008. I need to find a different location before that becomes a reality.
