Thanks for your response. I have a Caldwell chrono now. Seems to be ok. Clueless if it's accurate enough for this application or if I need to do something else in that area as well. I'm quite honestly a bit overwhelmed when I add up what is needed not to mention the learning curve.
My hand loading improved when I got my Caldwell but as I got better and more able to produce good ammo, it started to hold me back. Initially, mysterious variations in MV and SD got blamed on my lack of reloading skill. Eventually, I gained enough experience to recognize that occasionally it was the Caldwell telling me lies.
When you're able to get your ES below 10 much of the time and your SD down below 5, you can't put up with a chronograph which can't reliably determine MV. Sometimes I think my Caldwell did pretty well, but on other days it would show odd variations in the expected MV and once in a while give me a round 150fps fast or slow. With high confidence in my match ammo, I was finally able to raise the B.S. flag. Unfortunately, I couldn't always tell when the Caldwell was having a good and when it wasn't.
Missing a shot wasn't a frequent problem, but it did happen. The lies, some big and some small, were the real problem.
The solution was to purchase a Labradar; the best decision I've made lately. So far I have not seen a single MV which seemed odd. My SD's now are low with my good ammo, and not so good with my plinking ammo; just what I would expect. And they're consistent. And they make sense.
It also doesn't miss shots like the Caldwell used to do. Plus, unlike the Magnetospeed Chronograph, the Labradar doesn't mount on the barrel which negates measuring speed and shooting for precision at the same time.
My only regret is that I didn't buy the Labradar sooner.
