Can someone help me with understanding bullet stabilization factor # ?

I have a MAC computer and all the stabilization calculator programs that I have found will only work with windows. I can not use them, but I have found a online calculator that I have been using it is http://www.cbal.eu/stab.php?&lan=fr Should I be trying to select bullets that will have a factor of 1.75 for hunting ? What about solid copper Barns bullets, should I be using the 1.75 factor with those too?What about boattails and plastic tipped bullets, should this online calculator work for them too ? I am thinking of trying extruded powders and factors of 1.75( or close ) so that my hunting & target ammo will have a better accuracy potential in the widest range of weather conditions. I have many rifles from .223 Rem. to 338 Win. Mag. . Please let me know if I am correct . What do you think about this ?

You really don't need to worry about it.
Just be happy in the knowledge that there is absolutly no science involved whatsoever and know that it is all magic.

If you should want to continue to believe in such nonsense as elfs, fairys and Bullet stabalization then you could use this http://www.jbmballistics.com/calculations/calculations.shtml

That page should give you all of the foolishness that you need.
What for I have no Idea but knock yourself out.
 
I would highly

suggest reading Bryan Litz's new book. It will give you some perspective. Excellent reading.
 
When you use this one which I suppose is very good even as silly and make believe as it may be. Make sure that you enter the appropriate fields in caliber when it is asked for.
It also has your nose lenght, boattail length and all of the rest of that nonsense that you were asking about.

Take my word for it. It is all magic and whooppe dust.

I use the old timers approach. If the bullet is not stable it needs more RPM so I just add more powder. If that does not work then I have to go to a shorter bullet.

Over the years I have seen that higher pressure when the bullet exits the muzzle will de-stabilize VLD bullets. Longer barrels with less muzzle blast work better. Generally the higher the B.C. number the more spin is needed for stability.

I have had barrels that would shoot a Berger VLD bullet very good. Same barrel after I cut it off and rechambered was much shorter and the muzzle blast destabilized the VLD bullet. Flat base bullets work much better for me when the barrel has a lot of muzzle blast.

I have not seen that the math takes the muzzle blast into consideration. It is a factor.
