Hello all,

Without getting TOO scientific, can someone explain to me the practical uses of this calculator and maybe the differences in the stability categories when applied? For instance, what would you gain going from the upper end of 'fully' to mid 'maximal' stability?

Maybe a better question: does anyone even use these or do you just reference group size at various ranges to judge your stability?

Thanks!

It's pretty much just a way for Europeans to prove how "green" they are by throwing up web sites built from recycled HTML.

kis2,
I just figure the load data was developed to take it into account. And we have to give the barrel maker some credit for twist rate. One more reason I like the mainstream calibers. A bunch of others before me have a pretty well beaten path of what works that all I have to do is follow.
As with most rifles ballistics, in the end you still shoot to verify or prove the results.
I'm not advanced enough to worry about using the calculator. It is interesting though.

Playing with the calculator a bit. I am getting some wierd stuff out of it, probably because I am guessing at bullet length.

"The bullet is over stabilized and will keep parallel to the barrel and not the bullet trajectory on full shooting distance. It does not make any difference on short distance however on long distance causes rapid drop of ballistic coefficient and reaching the target with the tip pointing up."

"The bullet is maximally stabilized and will not lose it‘s stability on full shooting distance no matter what the weather conditions are."

"The bullet is not stabilized and will tumble on full shot distance."

It's like a thermos - how does it know?
