[QUOTE="J E Custom, post: 441891, member: 2736"] The chronagraph is the best way to examine not only the velocity but also SDs,ESs,average velocity, highest and lowest velocity. The only other way I know to get velocity is to shoot your load over the coarse (100, 200 , 300 , 400 , 500 , 600, and if you have the range on up to 1000 yards) with at least 5 shot groups at each distance to get a good center of group and match it to ballistics tables with your bullet. When you match all distances with your trajectory then you will have your muzzle velocity. This was/is also a good way to get a drop chart and an accurate BC for your bullet. All rifles are different and math just won't get you there. J E CUSTOM [/QUOTE]
