I have two 5mms - one 591 and one 592. I did the Schroeder conversion on one to a centerfire 5mm and ordered several hundred cases at the time. The other one I left original (the Schroeder conversion can be converted back to original if desired). Worked up a load with 40 grain ballistic tips but had to remove the bullet tip to fit the magazine. It shot incredibly well and killed a few groundhogs with it but my limited attention span had me on to other projects - may have to get it out and try and revive the interest?!!
Thanks for posting Barm - brought back some memories of days past!!
