Most of the time, my Chrony with the remote head does a yeomen's job. However, it will occasionally and inexplicably get into a funk that defies understanding and I've been working in electronics for going on 40 years. This past Wednesday, I was puttering with 300gr Gold Dots and VV N110. Over a short span of time, on a cloudless day, using the sun screens, running 3-shot ladder test, I got the following readings:
34gr
1905 (fouler)
1928
1932
34.5gr
1946
1948
1948
35gr
886.8
886.0
887.2
WTF?!!!35.5gr
2011
2015
1999
It's not the first time something odd like that has happened. More like the 5th time in two years of experimentation. That's 5 times too many. No idea why it went crazy. After the first shot, I recycled the power, but to no avail. And it's not like the sun coursed across the sky while I was shooting them. It was cold that morning, so I got all the shots off at 1 minute intervals and that included hand loading them one at a time. At least it was a good SD.
I'm not in the class of people who build car elevators in their houses, so price is important. Then again so is my time and mental health. For the amount of experimentation I do, I'd really like to find a make and model that doesn't cost as much as I paid for my 450B upper, yet doesn't pull crap like that on me.
I worked fastidiously making up those loads. No lie. 12 rounds and over an hour getting them perfectly matched, only to have some B.S. like that happen.
While affordable, the Chrony is starting to alienate my affection.
It was a new EverReady Industrial Grade Alkaline battery that morning, so don't ask...
Every time this has happened, it was during temperature transition from cold out of the carrying case to warm from sitting out in the sun. Regardless if that meant starting out at 30 and warming from the sun to 50, or starting out at 70 and warming from the sun to 90. Always during upward temperature transition. Once it reaches stasis, it runs like a champ. I've worked on problems like this at work often enough to know that they sometimes, heck most of the time, are not easy to recreate and hence troubleshoot on the test bench. Though we have a thermal chamber for running the temperature up or down, it probably won't go over well shooting through it.
So, if anyone has an affordable (I know, matter of perspective) make and model that they do not have this, or other anomalous problems occur with, to the point that they would recommend it, feel free to chime in.
