J E Custom, what chrony/s do you use, how accurate do you feel each is and what do you like and not like on each? I'm interested and the original poster may be in the market for one and interested as well.
I have and use the Oehler 35 P and the printer is a great feature for keeping records
unfortunately Oehler no longer makes the units and only builds military chronographs but
they will still service them.
The Oehler is the bench mark that all chronographs are compared to and I hope mine never quits working.
I have the sky screens at 4 feet and with the proof channel It is very accurate.( The proof
channel detects velocity loss over the 4' and alerts you if the reading is to far off with an
error warning that you may have a bad reading so you can delete that one and not
mess up the 5 or 10 round sample. (I like to sample at least 5 rounds minimum and
prefer 10 rounds or more for good solid SDs and ESs.
We can only hope that someday Oehler will get caught up with uncle sam and resume
building the civilian version again.
I have compared it with other chronographs and with the older 33 by Oehler and have
re-tested loads that were 15 to 20 years and it repeated the velocities withen 5 ft/sec (
normally slower).
