Woodleigh also makes a 550gn RN and Solid. I have tried the 550gn in 3 .458's and the .460 and like it so much I don't bother with 500 grainers any more.
I recall the magazine article you did about 20 years ago John on the 460 with 550grains on Bison I beleieve. A good read. What exact year was that anyway?
