I would like to formally introduce myself - Applied Ballistics

[DocUSMCRetired]

Many of you may already know what we do, the systems we have, and the Library Bryan Litz has created. I am joining this forums in order to give you guys first hand support. If you have any questions, or need any help please feel free to ask. I have an email below, or you can simply reach out to me here. I will be trying to keep you guys up to date on what is going on, and in the loop with the latest news. Sometimes I might even throw out an early teaser like this. To see the up-coming library of custom ballistics curves, and the full list of bullets you will find in the new book Click Here. Keep in mind that is only a list of the custom curves, their are many more listed with factory data in the software.

If you guys ever need anything reach out to me, I am always happy to help. I look forward to our future discussions.

Cool! Ballistics has always interested me. From bullets to ICBMs. I'm a child of the cold war you see.

As a former physics teacher, now retired, I taught a short section in ballistics just prior to deer season. Given the ranges at which deer were taken in the local area, the problem was more about accuracy and less about the bullet drop. But it did afford a physics lesson pretty much every kid could relate to and that created interest. If we'd only had computers and ballistic calculators way back then. The early '70s to be exact. But we did have "drop tables".

Good luck in your efforts here. The more people know about the various aspects of shooting the better.

I assume from your nick your retired military. Thank you for your service. Wife and I were both "squids" during the Vietnam war.

Welcome Doc,
Just so you dont get yourself sideways with the brass read this.

Welcome Doc, looks interesting, question though...

You refer to "custom curves" relative to faKeep in mind that is only a list of the "custom curves" relative to "factory data".

What are your general parameters for custom curves... common reloads, gaps in factory offerings...?

Best of luck in your new venture.

nipprdog,

Unless I'm missing something, the gun shop website you link in post #5 has nothing to do with the Applied Ballistics website and info mentioned by the OP in post #1. This just isn't helpful.

blarby,

Are you referring to post #1 or #5? I think #5.

 

[blarby]

Ahhh, I see my error

Let me get down to reading, as the apparent actual site and where my phone and fingers redirected me to are not the same place.

My apologies !

welcome doc!

i'll prob have a lot of questions for you soon. thanks for joining!

@ApacheCoTodd Custom means our full time ballistics laboratory has fully tested the round, measuring it in flight and getting very precise information. We do not use factory data, we use instruments to collect our own data getting more precise information for the round. The numbers we have are more accurate than what the factory releases.

@moxie you are correct.

@taliv I am always happy to help.

 

[taliv]

here are a couple questions for starters

1. for the applied ballistic apps, what kind of practical accuracy do you think is achievable?

2. in your measurement of the BC of various makes of bullets, how much deviation do you see between lots?

Excellent. Thank you for that explanation.

@taliv that all depends on you. The more accurate information you put in, the more accurate information you get out. I have had first round hits at everything from 400-1000m. Extensive R&D and field testing has been done, which shows the system works as long as you provide it with the information to work correctly. Almost every time someone comes to me who says its "off" I go over their numbers and inputs, and something was wrong on the inputs.

The second part of that I would have to talk with Bryan Litz about answering. Their are somethings that we try to keep in house. I can tell you this. Rounds are not just tested once. But they are tested again, and again, and again under different conditions. In order to ensure the numbers match up. And if anything doesn't look right, the Lab goes to work trying to find out why. So you are talking about the culmination of extensive testing.

Hey Doc,

Welcome to the forum. I have greatly appreciated the work and books of Bryan Litz, and I am a big fan of Berger bullets.

As my screen name indicates, I am also a fan of the .222. Any idea when you guys may have more accurate ballistic coefficients for the flat base varmint bullets in the Berger line? I read at the Berger site that these are calculated rather than fired numbers. I also read somewhere that it should be in the works to get some fired numbers and post more accurate ballistic coefficients.

Thanks.

no seriously, what kind of practical accuracy does the algorithm really offer?

how closely does your model match your testing?

asked a different way, what size targets do you get first round hits on from 400-1000m?

Cool. Welcome to THR. Lookin' forward to your input.

@Berger.fan222 Rounds from .17 all the way through .50 are currently being tested, for the next release. The current release covers .224 through .408. However the current testing going on covers exactly what you are asking for and will be released in the next update.

@taliv 1 MOA targets and sometimes smaller at their respective distances. I have used the software to get a first shot hit at targets greater than 800m with no sighters. The book we have, Applied Ballistics for Long Range Shooting, actually details how closely our curve follows the true path of the round. Their is going to be a slight variation in flight path from round to round as we all know. Which we can see in our shot groups. However I have on more than one occasion gone to the range, and started off shooting at distance, without any sighting rounds, without any 100 yard checks, got first shot hits. Most of the time now, when I do fire sighting in rounds, its at ranges between 300-500yards because I know our platform works. The last time I went out, we used an ISPC target., started at 600 yards, and worked our way back to 100 yards. Every round that wasn't my error was exactly where it was supposed to be. However in the past I have used 1 MOA round steels. Currently being replaced since they are all but destroyed, so we used the ISPC this past time, and got a first round hit at 600 with no warming up.

But to play advocate here. Rounds are not tested once, then forgotten about. Rounds are constantly tested. Over and over again. Then checked against previous data. If that data is outside our error range, then the data is gone through to see what went wrong. Our models, and the testing time and time again line up with incredible results. But it does require that the numbers that are input are just as good, as the performance you want.

It's been four months now since measured BCs were promised for the flat base bullets. Any idea where these are available. Of if they are not available yet, when?

 

[AR-15Nutt]

their are many more listed with factory data in the software.

that should be THERE !

just nit picking, looking forward for the info.

thank you Sarge, i too am retired.., U.S. Navy 25 years.
