Re: Question for a ballistics program user

Dave,
I got 1560 yds on the dot using your figures at a psi of 29.53, so something may be wrong with your program? I checked and double checked mine so........? Ian, could you run out and measure it off? hehehe. You must have posted while I was taking my sweet time eating and typing, editing the post before this.

All I need in a Kestrel is temp, wind and BP. No graphs and sub, sub, sub menus or other do-dads needed or wanted here. I just need to get this info.

The Oehler 43 I have needs the input for accurate BC and downrange velocity calculations too. The BP and wind meters are the ones I have to barrow from a friend right now who works on the North slope two weeks on two weeks off, kind of a pain when he isn't around. I can't find my Cabelas catalog so I don't know what features the Kestrel 3000 has.

If I change altitude to 10,000 ASL I can get to 1580+- and 65MOA elevation but the 1100 yard range only required 34MOA up and not the 44+- that Ian stated and the wind dosen't work out correctly.

What comeup does your program predict for 500 and 1000 yards?

On the GPS thing, the error on distance will be about 20 feet or so I'd guess.

Dave,
At 1100 we use 44 moa with 168's and around two less with 175's. The .300 Win mag and 190's is 32 moa. We haven't tried other calibers out there so that is all the come-ups that I have.
We have checked the 1100 yard distance a couple of times with lasers and it is very accurate - stood about mid-way and could get readings on the shooting shack and on the steel buffalo.
Good luck with your bear plinking.
ian
