It certainly looks similar to the old Lyman manuals I have that stop at 140 gr bullet size. I wonder if it could be a pre-Lyman Ideal manual back when Ideal maybe had a heavier mold??? At any rate, I certainly glad you shared it with me. Taking notice of bore diameter and the slight difference in case dimensions, this data certainly can be translated to my 6.5X54.

I noticed that I made 2 somewhat contradictory references above, I think the commercially cast slugs I have can be more accurately described as round flat nose. They are rounded with a small meplat. I've only fired a few thru the chronograph so far and have been handicapped this week with funerals, birthdays, and rain. Heck o'va situation for a retired guy to have to deal with. Maybe next week I can get some development done.
