Kestrel MV Temp Tables | Todd Hodnett from Accuracy 1st 

It's always a pleasure hearing from you! Thanks for watching. Regards The Kestrel Team

by any chance you could publish your data as im very much interested in temp tables in 22lr? many thanks

Once you turn on the mv temp table the MV will automatically change in direct correlation with the values input into the table as data points. If your ammo is at a different temp than ambient environmental temps, either colder or warmer, turn the MV temp on and then go to environment and change the environment temp to match the ammo temp. This automatically changes the MV in the gun profile to match the ammo burn rate variability at whatever temperature it is based off the data points you have input into the table. Then turn the temp table to OFF. Then go back and update the environment to capture current atmospherics. By turning the table off prior to updating to current atmospherics, we lock in the MV associated with the burn rate of the powder at whatever the temp of the ammo is, and then by updating we get the atmospherics required for ballistic calculations. If everything is working brilliantly out to 2500m I would suggest inputting a data point into the temp table of whatever MV you have and the current temp. This way if you turn the temp table on, and encounter the same temp then you MV will always come back to this value.

@@KestrelBallistics Can you please make a video about this? Cheers

@@KestrelBallisticsplease make a practical video regarding this

I would use the trued MV from the Kestrel. It is factoring in other things besides the MV when you are truing.

This situation is the perfect example of why you would want to use the table. By measuring the MV at a higher temp and a much lower temp, the Kestrel can determine the slope of the changes by temperature and thus make the proper adjustments depending on the conditions.

@@KestrelBallistics can the curve be an actual curve (temp v fps); or is it forced to be a liar profile with only a high and low end? There are 5 available inputs, so idk which is what the kestrel actually calculates with (a factor corrected linear curve or absolutely user accurate true curve)?

I also wonder a lot about my inability to use/find multi-BC's at different fps/distance. That was the entire reason I sprang for the Elite 5700 - best I can figure is buying the AB custom curve....but that still isn't a curve that is directly connected to my DOPE/my gun. In Strelok I can do all of this and for now at least my Strelok phone app is much more accurate if I get temp and DA from the kestrel....which is more cumbersome than I was hoping for given the $700 kestrel vs ~20$ app - Am I missing something I am new to kettle in general so could be I haven't yet found this option, would love to hear Kestrel's input if I can actually alter/make my own multi-BC table...

@@andrew13651 sorry for the late response. If you have the Elite, you don't have to buy the custom drag curves, just connect to our Kestrel LINK Ballistics app and find your bullet profile. You can then tailor the BC in the trans and subsonic regions by using the Cal DSF function on the Kestrel. There is no reason why the Kestrel should not be as accurate as Strelok.

Atmospheric will affect the ballistics and flight. Ammo temp can affect the MV which is one of the key bases for the atmosphere to affect. I think you are missing the difference. He's mentioning this as a data collection point to understand your ammo. Many times in So Cal its 30 degrees and later in the afternoon its 80 degrees you are correct in the ballistics charge and the density altitude but when the ammo is sitting out in the sun on the table that will also cause some big shifts if you aren't checking the MV through a chrono again.

You are correct that atmospheric temperature will effect air density and bullet flight. You are confused about the process of locking in the bullet temp in the MV-Temp table. What he is saying is, after determine the bullet temp you manually change the temp on the Kestrel to match the bullet temp then you turnoff the MV-Temp to lock in the bullet temp so it can adjust for MV. After this you will capture the actual atmospheric temp and by locking the MV table the bullet temp will not change to atmospheric temp. Now if your bullet is at the same temp as the atmospheric temp you will turn on the MV-Temp which will adjust the bullet temp to the actual atmospheric temps. And yes its all relative, as he mentions it all depends on how temp sensitive your powder is and the difference in temp in the bullet and atmospheric temp.
