SAAMI vs SAAMI II

[EasyShooter]

I got to ask another dumb question. What is the difference between SAAMI and SAAMI II. When ordering a reamer I saw in some cartridges there was an option for both. Thanks

What are a couple of those cartridges?

Revisions to existing SAAMI Accepted Cartridge and Chamber Drawings Link​

Occasionally a dimensional correction may be made to an existing cartridge/chamber design. In those cases the revision will initially be posted in this section until such time as the drawing is updated in the SAAMI Standards.

A cartridge/chamber design that has been previously subject to revision will have both an issue date and a revision date on the drawing.

My guess?

In 6.5 Creedmoor they offer a Custom Reamer, CIP Reamer, SAAMI Reamer, and a SAMMI II Reamer.

They have all the choices just to confuse people so we have something to talk about here.

Can’t get more detailed than that. Thanks. I didn’t study all the dimensions there but I am seeing a little more freebore in the SAAMI II reamer. Maybe designed for using heavier bullets or getting more speed by using more powder and having a longer jump to the lands like Wetherby chambers. ‍
