Re: CHRONO HELP
Chad,
On my second outing with the M2 I was set up at 10' with no issues from my rifle, but a guy next to me shooting prone would give the chrono readings from his muzzle blast. After that I always set up at 15' to keep the screens away from everything. Despite that, I would always get readings from the wind, and multiple readings from every shot, sometimes as many as six. It got so bad that I stopped bothering with shooting strings and would just write down the velocity after every shot.
Two weeks ago was the last time I got any consistency from the M2, and it was still very error prone. It's always been REALLY error prone, but it got increasingly worse. I understand the limitations of the technology, as well as many of the things that make them give errors, but this chrono would give errors or no readings at all at any time of the day; in shade or not; full sun or total cloud cover; screen covers on or off. It didn't matter. In my last five outings to the range, the first three gave no velocity whatsoever, and the last two gave very low velocities with error messages. Going by the last good velocities I got months ago from two handloads that I shot yesterday, it's apparent that they were way conservative as I had to come down pretty far in elevation to get hits, I mean like it wasn't even close. Yesterday was a picture perfect day to run a chrono and I didn't get any readings at all.
With the ProChrono and Beta chronos, I would at least get some data with intermittent errors due to the sun being full up, or shadows from sunlight filtering through the trees. I get that, but this chrono just doesn't work, and certainly doesn't justify the crazy price on the thing. Fed up with it, I ended the M2s time in this world yesterday by using it to hone my pistol marksmanship. My only debate now is whether to send the pieces back to CED with an angry letter.
