Hi Seafire,
An odd thing about stabilizing bullets, is that it is slightly velocity dependent.

A 1 in 16" twist barrel meant for 22 rimfire, but chambered in .223, will stabilize a 50 gr bullet, out to 100 yards.

A 1 in 14" twist in 6mmPPC take off barrel now in 6mmBR, will stabilize a 75 gr bullet out to 50 yards, but keyhole at 100 yards.

A 1 in 9.25" 7mmRemMag with 180 gr VLD, .. etc
