Any good free ballistic software out there??

[saturno_v]

I found here and there some rudimental web pages only for very simple ballistic calculation..

There are some more refined online applications for free?? Any downloadable programs??

I would like, at minimum, to be able to input BC, SD, velocity, bullet mass, compensate for temperature and altitude (air density) and wind deflection. and calculate trajectory and velocity at various distances with different firing angles.
Powder parameters would be nice to have too but not indispensable.



Thanks!!

Hornady's site has one that isn't bad -

Hornady ballistics calculator

It seems to have everything on your list except firing angle. I believe that firing angle (upslope / downslope) can be easily converted to an equivalent horizontal distance with some simple trig.

I recommend Exbal. For $70 you get a really complete ballistics calculator that will run on a PC, Palm PDA or Pocket PC PDA. This thing will do everything except cook breakfast. I really like the ballistic reticle feature, which lets you calculate what the Leupold (and other) "hold over" bars are going to do for a particular load. You can print little range tables to tape to your stock.

Here's a link -

Ammoguide.com got a pretty good one...try that.

pointblank is really good, a quick Google should yield a free download

I have recently been pointed to pointblank, and it appears to be very nice. It has everything you mentioned i think...
