[QUOTE="Stgraves260, post: 2593967, member: 19988"] It is very easy to misunderstand one another on here through messaging. Ill try to clarify things the best I can. Im not saying my rangefinders are better than a chronographs, it’s a whole system that I use that all works together. This part is just my opinion. If you are using a chronograph than you are probably using a ballistics Kestrel or other device that calculates your firing solution. When you plug in your FPS into your Kestrel device it will tell you the MOA,s or MILLs to adjust. Now when you are off target by a little or a lot you adjust your speed in your Kestrel until your bullet hits it target at what ever distance. ( Why do you do this? Because paper don’t lie ) You will have to do this because the measuring device that was used in your chronographs and your Kestrel had different tolerances/Quality control. Im guessing here but I think most people have read on a range finder or GPS it will say plus’s or minus 1 yard +/- 1 yard. Sometimes it +/- 10 feet. It depends on the quality of the measuring device that was used. Lets say you are loading for a 6.5 caliber 140 grain bullets and it takes 42 grains of whatever power to achieve 2750 FPS in a 24” Barrel. Now you put a custom 28” barrel on your rifle.
