Ballistic Program

[Sundown]

I have an old version of Ballistic Explorer 6.4.6 which does a fair job of predicting drop but a little off in some instances. I can input data including BC, elev., temp. humidity, MV, Scope height etc. and it will not give the exact bullet path at all points. I can vary the BC or MV and can not get the proper arc the bullet is achieving. This only happens in some shooters and not all. I'm wondering if it's due to the fast twist of some of my barrels. There's no place to input barrel twist or isn't this a factor. Anyone have experience with this?

I haven't found a ballistic program that will produce a dead nuts drop chart.

 

[Sundown]

I don't think I'll ever get it to project a perfect drop chart but was wondering if any one thinks twist is relevant. Are there Programs out there that input twist rates?

Any solver is only as good as the input you give it. Some arent even that good.

Getting perfect inputs, in my opinion, is just on this side of impossible. By the time you get them all nailed down, your onto another lot of bullets, powder, or its time to clean the barrel etc etc. . .

That said ive had very good luck using shooter, and now that the kinks have been ironed out of AB's solver its been proving to be very good as well.

Strelok Pro requites a barrel twist input.

Well said. Question - how exact are you trying to get?

Applied Ballistics is the best one I've found to get you as close as possible.

 

[Comrade Terry]

QuickTARGET does a good job for me. It comes with QuickLOAD.

95% of the calculators on the market (or free) are doing almost exactly the same math. It's a garbage in garbage out situation. Measure everything and you should be able to get good results.

 

[SheepDog]

Measure everything and input the exact values into any ballistics program and you will get a good approximation. Differences in air currents, local gravity, local air density all affect the bullet in flight. On top of the environmental effects you have the normal variations in the bullets and changing conditions of the gun.

If you want real info then look at your targets.

 

[Sundown]

Thanks for all your input. I'll take a look at Strelok Pro...Thanks Terry O
As for looking at the target, that's what I do now. I use the Ballistic Program to get an approximate drop, shoot and see where it hits and adjust MOA to match.
Thanks again

Strelok Pro has twist rate and even right or left hand twist.

It has trueing function for either adjusting BC or velocity.

I haven't found it to dead nuts accurate for my loads, but it gets me on paper and I can 'walk' it in from there.

With so many variables to input - I don't think you'll get perfection from any of them. Maybe there is one out there that is 100%, I only have used Sterlok Pro.

Another vote for Applied Ballistics.

. . . and the custom-calculated trajectories by Brian Litz.

I know what your saying. In the past iv had good results with shooter and two calibres. But my latest calibre, just doesn't line up. I'm not sure what to do. It's high at short distance and low at long distance. Or it's the other way around low at short and high at long.
The other calibres just fell into place.
