The reason for this, is because the 6.5x284 Norma was designed very similarly to the AI cartridges. It already has 0.0247" wall taper and a 35º shoulder angle. It would be kind of wasteful and pointless to fire-form cases to gain an extra .0123" wall taper and 5º more shoulder angle.Your right Eric...he makes a good point...to my knowledge no one has a 6.5x284 Ackley Improved or has mentioned needing one...
And, when you compare the 6.5x284 Norma to the original 6.5x284 Winchester wildcat, the Norma version is sort of an "AI" version.
