He guys I found a deal on a new chronograph so I bought it. Its the Competition Electronics ProChrono Pal Chronograph. Its very basic. It only shows velocity, high and low, average of shots and total number of shots fired. Getting extreme spread is easy (fastest - slowest). I downloaded a AP on my phone to get standard deviation so im good there. Im still pretty new to precision rifle shooting. I reload all my own ammo and started shooting F class last year. I never used a chronograph and decided its time to get one. What exactly should I be looking for with it? Im gonna compare my velocities with published velocities in manuals and try to get my ES close. What is SD? Is it important? What information are you guys getting with your chronographs and what do you do with it? Also when setting it up how far do I place it in front of my rifle muzzle? Im gonna make a tripod since I couldnt find a good one for sale online. The only one I found online had HORRIBLE review. The mounting holes is 1/4-20 so I can easily drill and tap those and make a decent tripod for cheap. Thanks.
