Range Report Dope Changes with, Elevation,Location, Temp Change

[dzlfarmboy]

Im going on a hunting trip in Montana in December and I know the elevation is gonna be higher, colder ect. Right now im at around 50-100ft elevation and 40-60 degrees. And my dope for my .243 is

200= .5 mils
400= 1.5 mils
600= 3 mils
830= 5.2 mils

Just trying to get an idea what to expect for a change when im in 0-20* weather and 2000ft elevation. I have the Shooter app I use.

Just curious if anyone has much experience with changing their elevation/climate and knows their dope real well to know what to expect.

Thanks Brett

I recommend you make up and print a JBM "trajectory card".

Go here: http://www.jbmballistics.com/ballistics/calculators/calculators.shtml

Scroll down to "trajectory card"

Fill it out, it has a field for you to enter various temperatures and Density Altitudes, and will compute trajectorys for ALL temperature/DA inputs.

Works great.

You should be able to change the altitude on the shooter ap. It should correct for it.

You're probably not going to see much of a difference if the conditions you provided are correct. The density altitude for the averages of both temp and elevation sets you provided were right around -500' to -1,000' DA. I doubt you'd see more than a 1/10 mil difference.

Yeah I plugged in the different elevations and temps in shooter and it really didn't change much. Just making sure it was correct as I thought it would with the elevation change.
