I have used JBM out to 1300 yards with a .308 and 1650 yards with a 300WM and many times to 1000 and change with 6.5 Creedmoor and it has been on all the time. I wouldn't sweat spin drift.

Re: Easy online dope
Wanted to let you know the "1000 yard" range card did not display correctly with the adjustment values. I am not sure what values it was displaying!?
This is just for the IPHY version. Don't know about any of the others.
Thanks

Correct, this program does not correct for spin drift, coriolis effect, or any of the other minutia. These errors are irrelevant with regards to the larger error of the G1 drag model for modern ballistics, and programs that correct for them mostly benefit from the feature as a marketing tool. In reality the wind is a much larger factor than spin drift at ranges beyond 600yd.
Like you said, it should be pretty much "on" out to about 600-800 yards, and beyond that you must verify the data and note corrections. It should get you on or near enough to correct onto target out to 1500 yds which is the farthest its been verified so far in real life.
This data is a starting point for making a real range card, and should significantly reduce the frustration of getting on target the first time out with a new load. The program solves the equations as accurately as any program, but the equations have inherently inaccurate for modern ballistics at extended ranges.

Thanks for the note and error report, it's fixed now. I had included the wrong header file and it was displaying mRads instead of IPHY. Enjoy!

Re: Easy online dope
This is a nice and quick program!! Thanks for the work. My only problem with calculated data is that it is always high when I go and shoot. I typically take it at about 80% and go from there.

What scope are you using? How is the scope calibrated? If it's in IPHY you might be off a bit.

Re: Easy online dope
A couple updates, faster computing, etc etc.
I've been thinking about adding a module for using Lapua's published radar range data on it, but I'm not sure how useful it would really be. Any opinions? Is anybody using it?

Re: Easy online dope
Having this program spit out a printable range card with BC, MV, and atmospheric conditions is soooo helpful. Thanks for the work you did and thanks for sharing it with us!

Re: Easy online dope
Thanks for all the appreciation, I checked my server stats and it had about 11,000 hits last month, so I guess some people are using it
and hopefully having good results too.

Re: Easy online dope
Thanks for the work dareposte. Rooky question, how does one choose the G? in input. I'm shooting 90g swift scoroccos if that matters. Should save me a bunch of ammo when I try to stretch out to 1000. Thanks again

Re: Easy online dope
Not sure what you mean about changing the G? input? You probably want to use G1 unless you're using a Litz G7 BC. If you're using a regular bullet with manufacturers data then just leave it as G1.

Re: Easy online dope
Thank you dareposte. I'm new to distance shooting. I've ordered lots of equipment to help "me" when "I" get better. Toys include an iPod Touch (already downloaded bullet flight) and a ProChrono which will be connected to a net book. I'm currently deployed (best time to order stuff) so these toys will not really see use until spring. <span style="text-decoration: line-through">I may still pick up a Kestrel, I currently have a simple Cadwell, wind speed and temp only.</span> <span style="font-weight: bold">Just purchased a Kestrel 3500NV from member ErikTaylor!</span> I really like the product you have produced, thank you Sir.

Re: Easy online dope
Nice! Thanks!
Few things got my attention, in metric mode:
-Wind unit is wrong. Its kilometers/hour, should be meters/second
-In Atmospheric Corrections, air pressure is in millimeters/Hg. Should be HectoPascals (hPa) or millibars (mbar).

Thats the only thing I´m using...why on earth not to use it if its available? Others makers than Lapua are different thing naturally. Lapua seems to be only manufacturer who has published (and measured?) that data for all bullets.

Re: Easy online dope - Now with Density Altitude
I noticed that a couple weeks ago. dareposte hasn't been on for about three weeks also. I don't know what is up. I liked the program, made a couple cards from it.

Re: Easy online dope - Now with Metric and mRads
went to go make a new card and the site is down???
Is it going to be up again?
Thanks for the past efforts it was great!

Re: Easy online dope - Now with Metric and mRads
Bad timing.
Anyone know how I can use JBM (or any other available ballistics calculator) to calculate my dope at various DA?
In JBM there is a box for temperature, pressure, and altitude. I just don't know what to input there.
I would like to order from Adaptive but they don't accommodate my 6.5 at 2750 fps., thus the homework.
Thanks.

Hold on. I think I found something from Lindy that I am reading through.

JBM should work great for you. It is asking you for data in order to get you the correct answer. Lots of factors for the computer to consider. You will not get a correct table (answer) without inputting the correct data.

Hey guys sorry about the busted link, I failed to renew the domain on time and they booted me out. I'll get it working again at the old address as soon as I can, but until then it works here:

Good shooting!

Re: Easy online dope - Now with Metric and mRads
Another feature added for the Density Altitude users:
There is now a link to a "Range Sheet" which runs the calc's at -2000 to 15000 feet DA and fits them on a single sheet out to 2000 yards.
Only available in English / MOA units for now.
http://www.direkon.com/DA/
Output looks like this:
Also, new expanded Density Altitude computation charts which are handy to have with this too:

And the Excel sheet behind the PDF in case you want to modify it or otherwise get the data out:
