Ballistics Programs (Web based & Downloadable)

Just a heads up about a PDA. The Palm III works fine for using Exbal. I see one on Ebay that includes the hotsync cradle for $19.95 ending in about 20 minutes.

Try PointBlank on your machine. It should work just fine.

Thanks Dave, I tended to use Quicktarget for making a drop chart but the Eskimo JMB one is better as it will show clicks for windage as opposed to the actual amount of drift in inches,

This is not web based or downloadable, but you gotta check it out. I just purchased it and so far love it. The H.R.T Tactical watch.

Dave,

Iv'e downloaded, "the thing" onto my PC and transferred it to a Palm PDA, very useful. However, I was wondering [img]/ubbthreads/images/graemlins/grin.gif[/img] If I zeroed on my range at 400ft above sea level, and then went hunting at say 1200 ft above sea level, would my shots fall high (or low) if I used "the thing" on my PDA with my rangefinder as there doesn't seem to be anywhere on the programme to save your zeroed altitude and change it to another altitude when at another level. Does this question make sense? [img]/ubbthreads/images/graemlins/grin.gif[/img]

If you're asking whether or not your 100 yard zero will be effected by a change in altitude I believe the answer is no. Your 100 yard zero could be effected by changing geographic locations (another discussion thread by itself) by changes due to altitude are about zero.

Changes to your ballistic data at longer ranges will (should) be effected by a significant altitude change. For these effectes you can change the altitude on the 'base data' page and recalculate.

Thanks for the reply Dave. The reason why i asked is that I zeroed for a competition recently at my usual range at 500yds and then travelled to compete some 100 miles south east, the range I was shooting at is about 1000 feet higher than my own. When shooting a couple of sighters into a sand bank at the same distance on the comp range I noticed that my poi was about 5 inches higher and had to come down one moa on my scope to compensate. I put this down to the change in altitude / atmospheric pressure. It got me thinking that if, as I intend to use rangefinder and ballistics programme when out hunting would my poi be out if I used "the thing" on my Palm.
