Thread: 7mm mag 26" velocity

If you are going to shoot medium/long range you need to start with some real data, zero it at a measured 200m so you know that part at least is right (there are a lot of unkonwn variables in shooting, you dont want your zero to be one of them) If you have a range finder, find a spot you can shoot out to a bit of range, zero it at 200m then fire groups at a series of ranges out to your max shooting range, measure the real world drop (ideally you will also record air pressure, temperature etc here, I dont know what you consider to be long range so not sure how important this will be for you), plug that into shooter or a similar programme and it will spit out your velocity
