Im going to build a 600 OK [collecting the dies ,brass etc] and have been told there are two versions of it ,I was only aware there was one ??? can anyone get me up to speed on this ? and if there are two types of reamers ,two types of brass etc .
I have seen a pic of a ''longer case'' version ,but I thought this might have been just someone's ''one off ''
Thanks for any info cheers

Talk with Wayne Jacobsen at AHR (American Hunting Rifles). Ed Plummer's original design is slightly different as I remember.

I wrote an article a few years ago about the 600OK. it covers both versions. If you are interested in it, PM me with an email address.

I've got a few photos also.
