The hornady podcast on external ballistics goes really well with the last part of the discussion on transonic and spin. They liken it to a child’s top spinning.
Why don't applied ballistics come out with a lab radar competition called the Enabler. This was fascinating, Jimmy asked a ton of questions I've wanted to ask. Great stuff!
I learned a lot! especially about using spin to correct for center of gravity and center of force. even without doing the math, this knowledge will help me to know why certain things are happening and how I might go about correcting them.
this episode brings suppressors to mind. are they bored out larger than the barrel to account for the transition between barrel and suppressor? is the segment of the bullet's trajectory through the suppressor too short to matter or are ballistics considered in suppressor design?
One thing I had read about Coriolis adjustments is from the data collected at the Army proving grounds at Aberdeen in Maryland. That effect only becomes a consideration past 1,000 yards. At 1,000 yards, your adjustment would be equivalent to 1/4 MOA.
Vortex Nation Podcast Great episode! follow-up question for your guests. It sounds like they describe the solver as moving stepwise from time 0 to time X according to initial conditions, velocities and such. But is the solver really using the Lagrangian under the hood?
Something else worth testing, for extended range volume fire. What benefits and downsides would there be from having aerosols of chilled Nitrogen or CO2 perhaps kept in cool boxes, to spray into the Chambers and barrels, say every 5 shots or so before barrels start heating up too much?
That would be an internal ballistics point. They are talking about external ballistics. However to answer the question a little. Barrel temperature will deform the barrel and change the point of impact so the more stable the temperature and the less variance in barrel uniformity then the less distortion. Yes rapidly heating and cooling a metal component will cause movement in the part and work harden the part. Think of annealing (heating and slowly cooling the part to soften the metal) if you quickly quench a metal part it will harden that part, quenching can be done with liquids or gasses. Doing this many times will cause cracking and shorten barrel life. Oxidation (rust) of the metal due to heat variance is also can shorten barrel life and distort internal ballistics. You want the least temperature variance to extend metal parts life cycle. But if you wanted the the most accurate tube (barrel) you could liquid or gas’s cool the part to keep a more stable point of impact. This is done with very high rate of fire barrels as seen on point defence missile positions on ships and air defence battery’s.
Here you go - from one of the precision LR guys here at the office - "Declination refers to the difference between true north and magnetic north (the earth’s magnetic pole is not at the very top of the planet). The Fury AB measures magnetic north, however the amount of variation that you are going to see between the two when shooting really isn’t going to make much difference until you really get into some really, really long ranges or if the error in direction of fire gets to be more than 45 degrees. Basically the difference in true north and magnetic north isn’t something that will be perceptible unless it is extreme and in his case it isn’t enough to worry about."
@@VortexNation you were looking for true North as that is the access that this is all about working off of. Since you are not working with magnetism, and the declamation would only be used for your Compass to give you a true north reading.
Have you guys ever discussed Package Accuracy, and its 3 elements, the fractions of minutes of each part of the package are the square root of the accuracy of the Platform - the rifle, plus the square root of the accuracy of the bullet load, plus the square root of the accuracy of the operator. A total package accuracy of a quarter of a minute, for instance, can be improved upon. 👍🙂🏴 For peerrsspeective, the Boers were shooting better than a quarter of a minute package Accuracy over 120 years ago,, which is a real eye opener.
DAMN Google hates me, they dumped my posts on this video, onto your AR 15 optics video. 😡 It's about a You having a Project Project to neck up the 6.8 Western to 7mm, and compare it with the 7mm-08 to see if it's any better for a new MBR chambering.
Just watching your year old barrel break in video. Bad advice in it. Never put copper solvents in your barrel, or you will have to break in the barrel Again ! Go to Gunsmith RUclips Channel GunBlue490 to watch his video, which explains how to treat your barrels properly. He REALLY Knows his Stuff. 👍🏴 PS. GunBlue490 has 2 really important videos on Gun care - Barrel Break in, and how to Lube your gun properly. Both well worth watching. 👍🏴
Tons of great info. And we even got the bonus of knowing what Matthew McConaughey would be like if he was born in the southern hemisphere

I just discovered the Vortex podcasts on Long Range shooting and ballistics. Hornady has an excellent series on ballistics, very detailed.

You guys should do a podcast about the 224 Valkyrie.
This is perfect. 1.5 hr drive to the range today so great to listen. 10 minute talk on 7.62x25 please!
I learned a lot! especially about using spin to correct for center of gravity and center of force. even without doing the math, this knowledge will help me to know why certain things are happening and how I might go about correcting them.
Awesome, freaking awesome.
I have read all the Litz books and didn't expect to learn anything new. I was wrong, though, and it was worth the time to listen. Thank you.
This is awesome information!! Thanks guys for another great podcast!!!👍💯
Thanks a lot , now I know how much I didn't know before. But in all seriousness ,. great Podcast!!!
Jeez , it's a wonder we hit anything at all....lol great stuff.
Go Huskies! I'm a fellow Michigan Tech graduate. Great stuff as always, guys!
this episode brings suppressors to mind.

Me watching this a second time currently like they called it 🤣 lots of amazing info!
Very informative listen.

Discussing ballistics of lead free bullets would have been interesting

website calculator does not seem to work, calculate ballistics button draws a blank chart page????

So my compass has its declination set to 13 degrees. How does that affect my direction of fire?
Should it be true north or magnetic north?
Now there's a heck of a question - we'll do some digging for you to see if we can find the answer!
