1000 Yard Shot - 300 Win Mag Winchester Model 1885

Using a Winchester Model 1885 in 300 Win Mag I make a 1,000 yard shot on the smaller Master's course target at Spirit Ridge Rifle Golf course. Here is a list of my equipment: Hornady 208 A-Max, Vortex Viper PST 6-24x50 MOA rifle scope, Vortex bubble level and Strelok Pro as my ballistics calculator on a Samsung Galaxy S4 phone with internal barometer, humidity and temperature censors. It appeared that I had wind directions in two different directions so I held for no wind on the first shot and hit just to the left. I adjusted for wind on my second shot and hit steel. Here's a blog entry on setting up this rifle:
