AIR DENSITY GAUGE

We used air density gauge when we tuned race car carbs--it helped us keep track of the air

I have been struggling with my 22 ARA shooting since the humidity and temp have soared--The humidity goes up to high percentage and my ammo hates it--well...I started thinking that if I had an old air density gauge I might could discover what the thresholds are for me and my weather and rig for swings or points at which I really start to see swings

Modern racers are all fuel injected or use computers for weather so I was hoping some old racer on here might have an air density gauge laying around gathering dust

Question, if you do discover that air density does affect the lots you are shooting how are you going to overcome that?
I believe you shoot factory class so you can't tune the bullet exit for optimum timing with a tuner.

My thoughts are to discover the thresholds where the ammo starts to react and hurts results. From what I have seen in the last month is a good ammo at 50% humidity may shoot very poor in 90% then go right back to winning when it lowers. So hoping to get a better grasp of what / when.
The only answer I can think of being factory class is to use faster or slower speed known good lots to “correct” and get better scores on that day with that weather. I have noted that faster ammo seems to do better in these extreme conditions of late but am not totally convinced. By that I am not talking what is on the box speed but verified by chrono speed in those conditions - Just seeking to understand more about what’s happening and hopefully come to some basic idea of what works when and why.

It has been suggested different speeds affect the exit timing and thus can be used as a “tuning” aid — that sounds reasonable but all I am aiming for is to understand how to see it coming — to figure out when maybe faster or slower lots could help

ARA around here usually allows some practice time before a match giving me time to test as many lots as needed to see what works better that day.

Wouldn't an Density Altitude measurement work for you, since DA takes into account humidity?

I use and track my DA every time I'm out shooting with a Kestrel Drop D3 and it works really well.

Wow that looks like the tool I need
Thanks !!!!

This was all done 20 years ago by some great shooters…all .to no avail, but hey, knock yourself out.
Still chasing lot speeds…..you seem destined to remain in the weeds.
Summer temps, humidity, those are conditions and related to your ability to shoot them, not lot speeds fantasy.
Sooner you understand this, sooner you progress.

Quite a few bench rest shooters and some F-class shooters tat I know track density altitude. My Kestrel Ballistics weather meter tracks da and a lot more.

So what is your suggestion for a factory class gun that starts shooting wild when temp/humidity gets really high?

If that’s the case, don’t know.
If you’ve been following along, highly probable that’s not the case.
Factory or custom, guns don’t go nuts with different weather and typically, neither does ammonia of quality.
Far more likely, far, far, is the fact that in the summer heat with mirage, often not easily recognized, you have far tougher conditions combined with rookie shooters, it’s not the least bit unusual.
I shoot, most often, at one of the single toughest ranges around and during hot/ humid days, come on over to watch 3-4 gold level HOF shooters occasionally brought to tears.
The answer, in a nutshell, get better, shoot lots of sighters, get better.
Even, factory class, tiny gun handling, less then great optic, crap getting in your head, in great cool weather you might slide on a couple, this time of year, you slip, you’re toast. Also, some ranges are more tolerant and some are real bears this time of year.
Finally, in the days of tough ammo, a consideration is what you think is a good lot might not be. Lot’s of newer shooters have never seen really top level ammo lots unfortunately,
There’s the answer that most long term veterans I know will tell you same……take it for what it’s worth.
You guys shoot factory guns,I shoot a 7.5lb sporter with a 6.5X scope…..trust me, it’s tougher this time of year in real condition.

85% humidity in the morning where I shot yesterday. I couldn't defog the windshield of my car during the 10 minute ride from the hotel to the range at 6:00 am. Some pretty good scores were shot despite the hot and muggy conditions. A 2450, 2400, 2350 (2), and 2300 (2) were shot between 3 shooters in unlimited (6 shooters total). There were several 2500's shot between 3 shooters in factory class (7 shooters total)

Dave, I know It's hard to not overthink things. I'm as guilty as anyone. But it think sometimes it's best to just go shoot and focus on the wind flags and try to do the best you can with what the weather give you. Too many distractions just makes thing more messy

Ok dude
I have a first , three seconds and a win today
All consecutive ARA
I ain’t in the weeds
Maybe not as smart as you but …

you got a handheld GPS?
My Garmin shows Baro Pressure at its current location (thats what I use)
or
you could get yourself one of these 3in1 gauges for $30 off ebay
