Easily understood, thanks.

FINALLY! The answers I had been searching for, thank you. I wondered how the 0.081 vs the 0.084 numbers translated to which was more BC. Plus, your visuals you presented helped a lot. Great job on hitting relative points for newbies like me. P.S. I watched a number of tutes and read for quite a while on sites and none were as spot on as yours.

I have a DVD from Brian Litz who is a ballistician for Berger Bullets with a degree in Aeronautical Engineering. That said the Applied Ballistics DVD explains sectional density and Ballistic Coefficient and how to set up at short range to improve your long range accuracy. His simple definition of B.C. is a bullet or projectiles ability to penetrate wind. Of course this gets into bullet design, weight, length, atmospheric pressure, wind, muzzle velocity, sectional density, outside temperature, the affects of different elevation which affects air density and correalis effect at extreme long range. For anybody really wanting to learn how to shoot long range I would suggest purchasing the Applied Ballistics DVD by Brian Litz. He has even created an app for smart phones that you plug in your data and the app will give you a Ballistic calculation for your shot. If your shots are off, there are corrections you can make in App that gives you a correction factor to improve accuracy. The dvd is really great and breaks all the different aspects of shooting long range starting with setting up your rifle at short range doing a tall target test to see how your scope is tracking and how to make corrections if the elevation is not tracking the proper amount based on how many clicks of elevation you use. It also will show if your scope is installed properly and the reticle is truly level and plumb. I could go on and on but if you want to shoot long range successfully I would urge any shooter to invest in this DVD!

Simply and fully exlained. Great job!

Very nicely done. Than you for the explanation.

Well done. A great explanation in everyday English.

Box truck and Ferrari example. Thumbs up right that because that explained it to me.

Thank's man, this was a great lesson.

Awesome explanation.

Great explanation of GC. Now I understand. Thanks for the info.

Great analogies thank you!

Best video on BC I've seen yet!

thank you for the wisdom sir....

Great video and information

Thanks. Very helpful to me.

Thanks, great info

Thank you Sir! If anyone doesn’t or can’t grasp or even comprehend everything that you said… Then they didn’t listen and are truly overthinking. Coming from an over thinker that’s saying a lot. Thanks Again 🙌🏼🙏🏼🙌🏼

Thanks 🙏

Thanks for the explanation. Now I just have to dig into the math and science. ;-)) Shalom/gw

Good stuff

thank you

Excellent. This has been like black magic to me.

Excellent Job, Thank You... ALASKA JOHN

Very helpful, only thing I’d say is next time show the bullets closer when you were comparing the two in the beginning I couldn’t really see them. Nonetheless super helpful

Well explained ! Thank you. If you are going to do this again, would it possible to include a real example of a higher B.C vs a lower B.C in the same weight ballistic pls (e.g 6.5 Creedmoor vs 270 Win)?

Top thanks

Question. Been researching ammo and settled on the Hornady 6.5mm 143 gr ELD-X. Why though do the specs show both a G1 and a G7 BC? Do the bullets come in different options. Second why does the flat bullet (G1) have such a higher BC than the boat tail (G7)? I thought boat tails were suppose to be better?

Think about it this way. How do you throwa football? Whats the shape of the football?

Thank you so much... do you think that flat base bullets can be used up to 500 yds. for hunting? I'm getting very tight groups with that ones.

I'm pretty sure Ballistic Coefficient is a percentage of either energy or speed maintained after a set distance. I'm not sure on he measurements but something like this. Eg.: if a bullet leaving a barrel is traveling 1000 ft/second and after it travels 1km it is travelling 580 ft/second then it would have a bc of. 580 or 580/1000

I’m trying to understand how these bullets compare to hollowpoints* I’ve heard that because of the hollow nature of the round, it creates a atmospheric barrier leading it to be more accurate* how does this compare with bullets of this style and why?

B.C.- a bullet or projectiles ability to penetrate the air. I’m correcting my comment below because I said wind instead of air.

He says Kudu, an animal in South Africa and Namibia. Also observing the Zebra on his uniform I can guess that he's operating in one of those countries.

So my 8mm at .560 isn't bad. Nice

BC is NOT "bullet-specific" and "bullet-exclusive" and "BC" depends on the BALLISTICS and conditions while a bullet is "in flight" which aren't determined JUST by its "shape". BC is calculated for a specific bullet FROM its in--flight "performance" and identical bullets loaded in two different cartridges both in that same caliber but producing different MV will result in the two bullets having two different calculated Ballistic Coefficients. They should be "proportional" TO velocity when corrected to "standard conditions" but without "load data" from "factory" ammunition testing in a real "ballistics lab" with controlled conditions such as Hornady's 300-yard underground test "tunnel", no "BC" can be calculated and lacking "factory" ammo "ballistics" and bullets "matched" to specific cartridges within a "caliber family" and designing specific bullets for specific cartridges and testing specific bullets on in cartridges they were designed for (no point in testing 100-grain .308-caliber .30 Carbine bullets in .300 Winchester Magnum) and being able to "average" BCs for a given bullet from multiple cartridges its "made for", any published "BC" is complete B.S. And BC is more accurately defined as a bullet's "ability" to "ignore" the "atmosphere" through which it travels and be "unaffected" by it rather than its ability to "slice through the atmosphere". In the real world, the "atmosphere" through which a bullet "flies" is constantly changing simply because even if nothing else "changes", its velocity does. And the slower an object travels and the less "inertia" it has, the less able to "slice through" or PENETRATE its "atmosphere" it is.

Thanks, but don't you think that accuracy is more important than high BC, when we chose an ammunition we should focus on both BC and accuracy.

So it's more aerodynamic.......maybe I'm wrong but seems like the gun world just came up with a new term for aerodynamic.

All bullets drop as soon as they leave the rifle barrel. There is nothing to keep them flying without dropping. The gravity takes over instantly. Then you have those people say they shoot 2 miles. Right............and the bullet " drops " on the target instead of going through the target vertically ! I want to see that bullet hit horizonal not vertical !

Lame could have just said it’s more “aerodynamic “ how bout that

Less that a minute - THAT'S NOT WHAT THE G1 AND G7 MODELS are - here's a guy trying to explain something (with which) (I had to sound intelligent like this guy) he doesn't understand. At least he tried.

Love the video, but you hunt deer with a 375, really lol.

Nothing I can understand here. If coefficient is important.......then why not make all bullets the best they can be ? Why play around with bullet drop ? Make all bullet with no bullet drop !

Sounds like a bunch of mumbo jumbo to me. Just point and shoot
