280 Ackley Improved?

[harps]

Just received 280 AI chamber reamer From JGS just wanting to make sure i bought the right one? Drawing says 280 Ackley improved SAAMI 2/1/08, headspace on this SAAMI version is .014 SHORT of the original Ackley specs. Im wantimg the Nosler version?
Any input would be great.
Thank you

Nosler version is .0143 short of PO Ackley's version.
SAAMI is Nosler/Remington version.

Hope this helps

The only difference it will make is for the dies you use. If you have dies for the original they will not form your brass because of the length issue.
