[QUOTE="EXPRESS, post: 1188435, member: 1441"] With the Shooter App you can add powder temp to your calculations, and it makes a huge difference to trajectory. Much larger than the atmospheric conditions. However I don't find it to be accurate to the actual ballistics. The Strelok Pro app lets you add a primary MV and then up to 4 more at different temps, so it can work out your powders' temp sensitivity. This seems to be a great method for establishing your actual variation, but I haven't had the opportunity to try it and verify it. So I wonder if the cartridge casing offers some good insulation to the charge inside or are the powders I use just very stable? [/QUOTE]
