Is the 'Chrony' chronograph ($97.00) adequate to determine E.S. in load development? How bout the Chronopal?
I know the Ohler is supposed to be the best but what is really required? I don't really about accuracy. It's the repeatibility I need for e.s.'s. I hear of folks bragging about single digit e.s.'s but wonder if the repeatibility is really that good on even the Ohler?
What say ye?

I recently bought a CED and have been very happy with it!

Jerry,

I have had a Pact in the past andit was very good. I now use a Ohler with proof screens and it seems to work well.Along with the advice that has already been given, I would like to add two other points. For comparisions, the same machine and setup would have to be used. Think about it, placement of the screens and their spacing has a great deal to do with the results. There could also be minute differances in the units or the screens themselves.
Lastly, and the most inportant, be honest with the tool. It is so easy to shoot 3 and see that the results are going to be "something to brag about" and simply stop right there. Sure this makes your confidence soar and a big smile will cross your face. But will this help you win matches. I do not know. I would advise a regime of 15 shot strings and let the chips fall where they may. This gives you a real world results to test your ammo and gun.All of my testing is done with 15 or 20 shot strings with a second backup string to confirm the results, do not want any "flukes" either.
I will add before closing, I have never shot single digit ES for a 15 shot string, but I have recorded SD of 3 and 5 on a fairly regular basis. My goal for a ES for a 15 -20 shot string is less than 20, and it must be able to duplicate the results.

However I could be wrong
