Ep. 044 - Bullet Drag & Ballistic Coefficient | Part 2 | 

Thank you Seth and Jayden and all the others that have contributed in past podcasts. Another great lesson digging into the nitty gritty of this fabulous sport of long range shooting and how an understanding the root concept of ballistics really matters. Showing how and why of things is almost a lost art considering our access to handheld 'super computers' and all the answers to all of our questions just a click away. I love the technology that we have and how much greater it will get, but I always like to learn about how these things really work. Consistently learning helps to keep the mind fresh. And no one is knocking how you do things, but like Jayden says - just for 'smiles & giggles' take a peek at 4DOF and maybe just give it a try. Not going to cost you a cent. And you just might like it.

Thanks for the shoutout! That 190 grain CX was absolutely devastating when it came to terminal performance. With a perfectly placed shot at 41 yards he was dead before he even hit the ground!

Bullet science is the best way to start the morning

My biggest lesson here is I can save money on a kestrel and just buy a basic wind and temp $100 one and be super accurate! More money for ammo for the win!

Thanks for these Podcast; it's always great to grow in knowledge. . I hope you gents have a great day

Hi Seth, Hope you are doing well. You're doing a great job as video host. ;-)) Shalom/George Wilson.

Great series. This is a little off topic, but love your wide selection of Hornady round balls.

Once again-excellent series!!! I can't wait for the next series -- when you start expanding the principles behind 4DOF!!!👍❤

Love to here your thoughts on consumer grade Doppler.

I'm so confused. My world has been shattered 🤦‍♂️🤣🤣🤣

Thanks for all the good info.

When you are talking about changing the BC or the velocities. You are referring to just changing the data in the program? Because you cannot physically change your load to get the data you want out of the calculator. These podcast are full of Great information. Thank You.

Thanks for putting this together. It would have been helpful for me if you’d shifted the ‘model bullet curve’ left and right to show how it lines up with the actual curve when variables (temperature/velocity) are adjusted. I think it would highlight the areas that the ballistic solution is improved and where it is degraded by the ‘adjustment’. I love 4DOF but there are still bullets that I like to use that aren’t included in the library yet. For those other bullets adjusting something (BC, Velocity, temp, DA etc) is the only option for improving the predictive curve. Also, I still make hard data cards for everything (even when using 4DOF) for my actual shooting (steel and critters). This definitely helps explain why things needed ‘truing’ in the past. Thanks again!

seriously looking forward to the how to setup/use 4Dof thanks guys.

Then there's gravity. If you're walking across flat land gravity is a vertical vector. If you're near a mountain an additional horizontal vector is added.

It gets worse because not only does performance of the bullet change with temperature/air density but powder burn rates change with temperature. I was told in college chemistry the rate of a chemical reaction doubles for each ten degree increase in temperature.

Had my first shoot @ 600m...90 degree cross wind 25mph from left😨. Tried nosler RDF'S 168 grn and Berger 155,5's.....nosler did not do well at all, went all over target. 155's were much more stable, even in that wind. Can you explain why?

Where can we obtain or could you please share with us the educational material used in the video? Thank you.

Where can I find the ultimate guide for BC on ALL rounds to include non-Hornady rounds?

What is the verdict on Applied Ballistics with their doppler radar collected custom drag models? Isn't that fixing the problems with standard BC based calculators?

I'm confused - doesn't your data show at (44:20) that at 30 and 80 degrees an adjusted BC of 316 and an adjusted MV of 2710 FPS that the adjusted solver predictions are within 1-2 inches of the actual drag curve at 1,000 and 1,500 yards? Isn't that pretty much insignificant?

If you are truing MV 100 fps something else is wacked. We usually talking small differences.

I ave tried to get the name an way to get the program to deal with these issues. I cannot decern the name from within the youtube. Please advise how to get and what it is called. I have a labradar and need to get full range trajectory for my son who wants to be competitive.I am currently locked out of the Hornady site for an unknown reason. I have wwritten to the webmaster on this issue separately.

Is there a way I could get my own bullet drag modle inputed into 4dof?

All of this information is wonderful there’s no doubt about it but when is the app going to be accessibility compatible so that it can be used by everyone?

Great content you guys have been putting out lately. I don’t understand why you developed the ELD-M with a polymer tip, instead of streamlining the BTHP bullet. It seems like you could swage or draw a bullet into any shape you wanted, without the added expense of fitting a polymer tip. Since terminal performance doesn’t matter with a match bullet, why the polymer tip?

🥴 great work tho An buy the way could you guys get some 150gr interlock in .312 aka 7.7 303 diameter projectiles shipped over to Australia my no1 mk3 303 is hungry lol

It is pretty funny, spend a couple hundred dollars on a chronograph then turn around and ignore the data you just recorded because the free program you are using isn't right and it says to change the velocity to "fix" the issue. Hell if you are going to do that just sell the chronograph and guess at velocity.

I am bitterly dissapointed. I came here for knowledge and all I got was a sales pitch. 4DOF might be 100% accurate, but it is so difficult to use and (unless I am missing something) lacks so much of the extremely useful features of some of the BC calculators available.

BR guys load at bench for a reason.

Every inch mattes. I hope that’s not true. Gonna be hard to find a girl.

WHY CAN’T I FIND ANY 6mm ARC PRODUCTS TO RUN MY GUNS. COME ON GUYS, SUPPORT WHAT YOU DEVELOP!!!!!!!!!!
