Well, it sounds like there are some that made it out to users. How are you guys liking them? I'm sure they must be awesome after having to deal with the problems of lesser technologies. After using standard screen type of chrono for several years now, it is apparent to me that this technology has a couple of main important advantages over others that have been in use so far. You guys probably already know what they are.
Here's a great read on chronographs, and the Labradar is mentioned.
Now here's a kicker that shocked me last night, off the subject of chronographs but directly related...from the famous Houston Warehouse Precision Shooting project, an excerpt of what Dave Scott wrote:
Myths Busted:
- Powder charges, as long as they were fairly consistent and bracketed within a couple of grains, were not important. He threw all of his charges with a Belding & Mull powder measure, and for one experiment he shot groups using three different powder measure settings (51, 52 & 53) … all three groups were identical.
I just find that hard to believe unless the 3 charge levels don't produce significantly different velocities. And wouldn't the effect be more or less pronounce by the burn speed of the powder? Even if you're in the middle of one of Newberry's OCW nodes, +/- 1 gr should make a significant difference, no?
I'm not Bryan Litz or Dave Scott so I don't understand how significant variances in charges don't make a difference in group size. We're not just talking groups of charge levels, we're talking random charging because they mentioned throwing charges from a powder drop vs weighing each charge results in the same accuracy. Sorry, but my mind has been blown. Why am I weighing each charge to within kernels of 4831 or Varget if I could just throw them? My experience is that the latter decreases accuracy. For sure it affects velocity in all cases I have seen over thousands of rounds hand loaded and speedchecked.
If this conversation should be over in the reloading section, sorry for the distraction but now I'm a bit puzzled about weights, speed, consistency which I thought all affected accuracy. Everything is going out the window.
My first chrono was one I designed and built in 1986 (wirewrap vectorboard circuits), but it along with the Z80 based PC I used were destroyed in the Loma Prieta earthquake in '89. I lived 1 mile from the epicenter. I never "productized" it and raising a family and work reduced my shooting to hardly ever for some years back then. Chronos really aren't very complicated.
