longest .224 boolit a 1-14" twist will stabilize ?

I realize velocity is part of this question, so I'm looking at roughly 2000 f/s ( .222 Rem) or possibly a little faster with the alloy I have available. I've got the original Bator and the new bore rider from Lee and was wondering if a heavier boolit would stabilize in the slow twist barrel.

This is what the Precision Bullet Design and Evaluation software calculates 0.5435" as the maximum bullet length that will stabilize a 0.224 caliber bullet launched at 2000 fps from a 1:14 twist barrel using a Stability Factor of 2.



Below is an excerpt from the Bullet Design Help Files that pertain to the Bullet Stability Factor calculations.
Calculate the Bullet Stability Factor

The minimum calculated stability factor to stabilize a bullet has
been determined to be 1.5, However the minimum safe factor is usually considered
as 2.5. Therefore a default value of 2.5 is used as the starting factor in the
calculations.

The Bullet Stability Equations of Don Miller that include muzzle
velocity, bullet length, bullet weight, twist rate and a stabilization factor
have been adapted to calculate each one of the factors if all three of the
remaining factors are known.

The Twist Rate, Muzzle Velocity, Stability and Calculated Bullet
length field value entries are optional. They may be used to calculate an
optimum bullet length that is appropriate for the caliber and useful muzzle
velocity of the application

Hope this helps.

Thanks for the reply; I see I'm not going to be able to stabilize a heavier boolit without going to a very low b.c. design.
