Long-lasting, tough and extremely rugged - military, law enforcement, and firefighting professionals rely on the Kestrel to perform and endure under the most demanding circumstances and in unforgiving environments from the combat frontlines to the wildland fire lines. Whether serving in the line of duty or active in the pursuit of your passion, you can depend on the accuracy and durability of Kestrel meters under any conditions.
how about using that dry erase board in the back to show how you come up with the windage. You saying at 700 youd have to add .1 mils at so many mph... make it make sense!... if my quick call is 5mph, wind is blowing 10 mph (from left), my range/distance is 700 but kestrel is showing an .81 for wind adjustment, what should by quickwind adjustment be? 1.3 mils? i am guessing at this point
Ridiculous over complication pushing up the price with a ballistic solver of dubious accuracy . The entry level should just be a weather meter and nothing else to break down and links to fail etc etc. Kestrel has had problems with their connectivity . I am really put off buying a new one now .
I only want a good weather meter not a ballistic program . Why do they have to ruin a simple easy to use product with over complication . The base model should just be a weather meter nothing else .
For a long range ballistic app only having a G1 drag function is very poor . Most long range bullets fit a G7 drag function . It sounds to me like the ballistic program is fairly useless . Why can't you just make a good weather meter and leave it at that . The cheaper model does not need useless gimmicks . If your using a bullet that does fit a G1 drag function then it may be ok .
youre explaining great stuff.. However please show a practical on how you for the wind dot value. i understand how it works, but this video would be more beneficial on how you got the values.
So wait, the Kestrel is saying to hold at 6.75Mils at 800yards... yet you say the Kestrel is saying to hold at 6.88 mils for 800. You take the shot and make .5 mils needed adjustments on the drop. I just want to make sure when i start Truing i am using the numbers in front of me. Good info
great video... Question; Cal MV in your Kestrel was 859 yards. your using 765-900 yards and decided on 800 for truing. Why not use a distance between 859-730? With respect to the 15% range.
Hello ! I have a question about the wind: if the bullet flies through a wind corridor, will it maintain the new direction of flight or will it continue to follow the old direction of flight? after it has completed the sideways drift. I think it will take the old flight direction because it straightens the nose again and so the tail deceleration no longer has a sideways effect. is that right?
If I use the 4DOF app on my phone, is there any reason (other than simply having the ballistic calc on the kestrel instead) to upgrade from the 2700 to any of the other models?
I’ve always used scope shadows to determine the optics center, especially if shooting cheaper scopes with no parallax control. It’s a great technique to check yourself so I still use it on high end scopes as well
Many giys in high school - I dont need to know all this math. Ill never use it the rest of my life. Guys after getting into long range shooting - I woshed i oiad better attention in math class.
Awesome video....my question....I shoot a 6.5 Creedmoor out to about 950 yards at my local range. If I am not shooting past that distance and past the supersonic range, do I need to true the rifle at all? Thank you...hopefully not a silly question.
@lBallistics Great advice....I am hitting at 950 yards on a target that is about 3' x 3'...It is hard to see where I am hitting, but we have a strobe that lights up when the steel is hit. I am happy that I can at least hit the target that far out! I am inconsistent with my hits, maybe 2 out of 4 hits at that distance, and I dont know if it is technique, or just not having the rifle trued for consistency.
Every generation is a different situation with needs. It's a shame our own government doesn't recognize that our warriors equipment needs to change with it.
How do you true up a bc. I was shooting at 1822 yds yesterday with 300 norma mag and my kestrel told me 19.5 mills and it the target was at 19 mils. Thanks
It really depends if your bullet is super or transonic at that distance. You would use CalMV for supersonic and CalDSF for trans/subsonic. I would point you to our schoolhouse: kestrelballistics.com/schoolhouse
Got a question that i find no answer for .. in kestrel 5700 Applied ballistics , how can you calcylate the angle of a moving target? ..Awsom vids .. thanks for all ur time and efforts
I was looking for some info on my new Kestrel and stumbled on this. I have been looking for something like this to explain basic PRS for ever. GREAT 3 episode series. Thank you.
The Ruger model has some preloaded rifle profiles in the application. But you can certainly use other types of rifles, you just need to input the parameters manually.
This is cool, I love that the Accuracy First guys are still trying to find better solutions for quick wind/hold formulas and its really easy to look at ballistics tables and figure out your own speed drop number and that will give you a quick and easy "close enough" hold out to 400-600yds depending on the B.C. For a good place to start take the G7 BC of your bullet and shift the decimal point one position right or divide your G1 BC by half and that will get you close. Obviously the higher B.C bullets are more efficient so you might want to try 40% of your BC instead of 50%. For example I figured out my "speed drop" for the 77gr SMK with a .177 G7 and a .376 G1 with a 100yd zero and its 1.5 from 170-280 and 1.7 280-480 and then past that it really starts dropping off to basically zero "speed drop" 600yds with that bullet at 2750 is 5.98 MIL of elevation. So my max "speed drop" calculation range is 480yds with that bullet/zero/velocity/sight height. I could split the difference and call it a 1.6 but I was keeping withing the .2 MIL error and even with two speed drop numbers and two ranges that it works that's a super simple data set you can write down and stick inside of a scope cap. If anyone has this program I would love to see how close my "speed drop" number and max effective range are to what the program says they should be.
If you're only going to shoot close range of 400 or less yards, then no you probably don't need it. If you're intending to shoot beyond that range and setting your rifle to a 100 yard zero then yes, you'll need to record and input the conditions. It matters.
