RE: Falling bombs and the rise of a nation - Six: Drawing lines and pulling back
Thanks, good History! When they did bring their invasion fleet, they had a little trouble in the Coral Sea....
The fighting you guys did in New Ginea was some of the nastiest in the war. The conditions were stunningly bad, almost worse that the enemy! Sitting on top of it was New Briton (Rabaul) in Japanese hands....
We had a different kind of condition problem in the Allutians, but still brutal.
Does altitude enter into windage, due to decreased air density / wind pressure?
Yes, the PNG campaign was horrific. You know I've trekked the Kokoda Trail right? I think you saw the posts a while back right?
Altitude affects the shot yes. Mostly the drop, not windage. I factor in the altitude, temperature and humidity as a single figure called density altitude (DA) which can make a massive difference to the shot.
Depending on the range the elevation dial can be massively different. I think the windage isn't all that different as you will see below. Greater distance affects windage more than altitude.
The chart below is straight off my ballistics app and shows a DA of 1200m. The rifle is .243 CTR.
You will note the windage isn't affected too much as I set the wind at 1mph full value (90 degrees)
Now look at this one where I set the wind at 10mph full value...DA 1200.
Now the same as above with a DA of 200.
The settings...

I would love to dive in Iron Bottom Sound to look over the lost ships from both sides. That sounds like a 'Nice' hike for sure! I have a 7.7mm Ariska that came from Ie Shima. My Father was there, in a repair unit. A group of starving Japanese got behind our lines, and surrendered to his unit.
Surrendering most of the continent without a fight was a crazy idea! I am glad they changed their minds.
I was just wondering because they correct the power curve for wind generators up in Denver (5000 foot altitude) for a reduced output.
It still surprises me that the velocity drops off so fast, I need to get a good calculator for this.
I recall your dad served. Also your father in law? Was shot in the arm? I'm sure you have some stories from them, although many don't talk about their experiences.
Yes, velocity drops away quickly. I find it fascinating how a few degrees and some humidity can make such a dramatic difference. Get it wrong and it means a miss. In some situations missing a target can have monumental ramifications.
I use Strelok Pro for my ballistics. I'll do a post on it someday.

Dad was wounded in the arm, Her Dad was shot down twice in a B29. Great fun in the 1940's.
Humidity is a variable I had not considered...still learning, SMH! Temperature is something that lowers the air density due to expansion, so I can see that changing drop. Working to wrap my arms around these variables.
More work to do to properly use my toys at long ranges. Lots to learn still, but I am enjoying the learning process!
Does Strelok Pro un on the smart phone, or is it a separate unit?
:)>That's right, I recall now...The B29 crewman...Good that they both survived.
Strelok Pro is available for smartphone. I run it on my Samsung S9. I think it's also available to iOS as well. if you have any questions email igor@borisov.mobi as he is the developer. A Russian chap. I've emailed him with a question or two and he gets back to me really quickly. Seems a good sort.
I will look for it, what will it cost? I like responsive vendors! Besides, I need a Man named Igor on my mailing list....
:)>Hmm, I cant recall the cost and it doesn't show up on the Playstore now as I already have it installed. It was not much. I'm thinking $30 AUD or something like that. Worth the money though. Here's the website.

Thanks, I bought it on Amazon. having amazon trouble downloading it; BUT that is not the software's fault, just amazon being amazon!
$12.40 on amazon....
