Default .338 Lapua Magnum Trajectory out the 1500 Meters

I'm looking for some ballistic charts illustrating the .338 Lapua Magnum's trajectory out to 1500 meters and have had a hard time tracking them down. Does anyone know a good website that has this information or a tragectory calculation program that allows you to imput data out to that range. All the ones I have found stop at 1000.

Thanks In Advance
