Can someone run this through their ballistics program?

Hi folks, I'm using point blank and would like to double check the figures I'm getting in comparison to a "name brand" ballistics program. If you wouldn't mind going to the trouble with a program other than point blank, I'd be much obliged. What I'm after is only the total drop and velocity and ft-lbs remaining at 1000 yards with a target distance/zero of 250 yards, thanks!


Here's the load and data:

.243 Winchester

2950fps

105gr AMAX- BC .500

70 degress F

Target distance 250 yards

Scope height 1.5"

Thanks a lot!

JuniorG you're a life saver, thanks! My numbers are very close, so now I have confidence in point blank :)

Use JBM

It's free for download, too, so you can run it on your own web server.
