Chrono No-Nos: Remember this Device is a Tool, Not a Target

accurateshooter.com target chrony shoot chronograph damage chrono

“Shooting Chrony” is a product name. “Shooting Chrony” should not describe (post-mortem) what you have been doing to your chronograph. Sooner or later all of us may make a mistake, and ventilate our chronograph. With luck, the bullet just “wings” your chronograph, and the damage is minor. But if you hit the unit smack dab in the middle, you may have to retire your chrono for good.

A while back, Forum member Jeff M. (aka “JRM850″) experienced a “low blow” that put his Shooting Chrony out of commission. With tongue firmly in cheek, Jeff started a Forum thread entitled Chronograph Not Picking Up Shots in Bright Sunlight Anymore. Looking at the photo at top, the problem is obvious — he ventilated his Chrono.

This was Jeff’s first chrono kill in 23 years of use, so we shouldn’t be too critical. Jeff explained: “I didn’t realize a friend was shifting from a 300-yard target to 100 yards.” The agent of destruction was a low-traveling 58gr V-Max running at 3415 fps. What happened? Well, when one is shooting at 300 yards, the trajectory will be higher than at 100 yards. We should say, however, that this may have been a low shot, or the 100-yard aiming point may have been placed lower to the ground (closer to the bottom of the target frame), as compared to the 300-yard aiming point.

Other Forum members offered some sarcastic responses:

Try it on an overcast day – it might work again.

It looks like the V-Max performed just about as advertised.

Aww…a little duct tape and some Super Glue and you’re good to go.

SHOT Show: Oehler Model 35P Chronograph Lives On

Though it is a 20-year-old design, the Oehler Model 35P Chronograph remains one of the best chronographs on the market. By employing three screens instead of two, the 35P takes two (2) measurements of each shot — adding an extra measure of reliability. It has very simple controls, so you don’t need to bring a 100-page manual to the range. The Model 35P features an integrated printer that conveniently records every shot and calculates Average Velocity, SD and ES for your strings. We like having the “hard-copy” output from our tests. This way we can simply staple the our paper record to the target and nothing gets lost.

Model 35P is Back in Production
Oehler Research decided to phase out the model 35P Proof Chronograph a few years back. But consumer demand never abated. In fact, the prices of used units started to climb. So Ken Oehler decided to bring back the model 35P, and we’re glad he did. In the video below Ken explains that the Model 35P is back in regular production, now that his company has found a source for printer components. The Model 35P, complete with printer, skyscreens, and mounting rail costs $575.00. Ken told us “If we knew how to make them cheaper, we would … but we make ‘em so they work.”

If you already own or use a Model 35P, be sure to watch the video through to the end. In the last minute, Ken Oehler demonstrates how to position the metal support that holds the paper roll. Putting this support in place can be tricky to say the least. But the video shows how to accomplish the task quickly, without losing your temper.

Another helpful tip, provided by Ken’s wife, will help you feed the paper into the machine. Simply take the end of the paper and fold both left and right sides in toward the middle, forming a ‘V’ (like the nose of a paper airplane). This will then advance much easier through the printer’s internal spools when you load new paper.
