Episode 99: how do you measure bullet speeds at distance

[ViP]

Hello. During the episode, I heard you guys talk about the speed of a bullet at a specific distance. How do you calculate that? Thanks.

Using your ballistic calculator it can estimate your MV at any distance based off your input of your starting MV. You could calculate it yourself but it’s a long formula.

Thanks. For a moment I thought they were measuring it with doppler. Ignorance is bliss...not

Ain’t no one got that kind of money, well except the manufacturer

Actually it's not that hard. Just reverse engineer it. What I mean is that your dope will tell you mv at range. It's not like snipers are gods. Just simple math. And the reason for simple math? For people to lazy to find out what is actual. So just screw math and find out what it is by shooting all yardage and seeing what your dope is. Or just use an online app and then you have something to blame when you miss. Because you will.

I’ve seen guys shoot over a Ohler st 1000

Ummm...doesn't the Ladradar measure velocity at distance?

Mine measures a tiny bit out, but no way to trigger reliably at distance like at a 1k range. The acoustic chrony pics up if super sonic.

Interesting, as I thought that that was the main advantage of a Labradar. Good to know (thanks!).

I have all this stuff,

The Labradar the best range I have gotten a reading is 72 yards... does not work for downrange in its current form

An Oakwood Tech H Bar and my software has the MV feature turned on, it's complicated, and expensive but works

An Acoustic SuperChrony can work a bit but you have to be really good at lining it up and you must be supersonic

Reversing the numbers using software is the easiest if you have the dope to work the numbers. Which we always have the dope.

You can also use the new Shotmarker target, which is not as pricey as the Oakwood unit, plus you can make frames and size you'd like.
