Ballistics programs:


I am interested in a good ballistic program. I have ON TARGETS 2.0 & 3.0 and Lock Stock and Barrels ballistic programs. All of them give different readings (there close) with the exact same load data loaded into them. They all keep up with each other until around 600 yards and then their calculations go south and inconsistant of each other. I find my rifle works well with them out to that range, but after that I do a lot of walking and recording. My findings are nothing close to what the programs offers. Also their wind and up/down hill calculation are no where near what my findings are. Any help on a good program would be appreicated.

RE: Exterior Ballistics Program

I am currently using the Sierra "Infinity" software. You can get it with the Loading Manual incorporated, but I found that unnecessary.

The best thing about it is that you can run ballistic comparisons at different ranges, under different conditions, for several bullets at a time.

I.e., if you want to compare the Berger 73 grain LTB with a 69 SMK and a Hornady 75 A-max, it will print a chart with one bullet path in blue, one in red, and one in green. Most excellent for comparisons.

You can also change the environmental factors, such has humidity and temperature, to compare their effects.

Runs about $35 US.

Jeff,
As far as using a ballistics program to set your dials, your doing the right thing by shooting and walking and recording. They will give you a ball park figure and save you some ammo to get you on target, but from there its all apples and oranges, because all guns are different. You have to burn powder to learn your craft, there are no easy ways to do it.
