[QUOTE="J E Custom, post: 523010, member: 2736"] I can only say this about chronographs. You get what you pay for. There are always times that they may give you trouble because of light and proximity to the muzzle, But these things can be over come with ease. Any instrument that samples 4 million times a second should be very accurate. (Some sample less per/sec). When you can measure 1 ft/sec difference between shots that have a velocity of over 4400 ft/sec (My fastest cartrige) I would have to say they are indeed accurate. Bullet makers have a habit of claiming higher BCs than actual. The chronograph can verify the actual BC by comparing the velocity to the actual trajectory. Once this is established your Ballistic calculator can be astonishingly accurate. Without good data It is just a guessing game. I am sure it can be done ,But it seems like it is subject to error and inconsistent. I use my Chronograph for lots of other things beside velocity and find if invaluable. It has saved lots of time and money developing loads and comparing pressure effects. I could not and would not do without my chronograph. Just my opinion. J E CUSTOM [/QUOTE]
