I want some software to help me consider caliber comparisons and am focused mainly on external ballistics. I'd like to be able to look at long range trajectories, wind drift, etc. I'd prefer for it to have a library of information (bullets w/ coefficients, standard loads, etc.), but want the capability to add data as well. I really want it to be able to graph / compare different cartridges at the same time. It would be great if it had reloading data too. Free is great, but I'd pay a little bit too.

Anyone have any favorites?

Here are the notes on software that I saw:

Sierra Infinity:
- Data on Sierra Bullets
- Compares five bullets

Load from a Disk:
- Internal ballistics
- Not what I want, but looks neat

These should cover what you need.

I use "Trajectories" for external

Quickload is hard to beat for internal.

If you want something that is free try Pointblank, you can download it today and play with it.

I use QuickLoad. It is extensive!

pointblank is free and does what i need it to do very well - have heard many mention quickload but i think it costs some money.
