And here I was thinking I was setting the world on fire with my rudimentary loading datas, LOL

I got a look at a Lyman reloading handbook today, and they listed similar data for 180 grain bullets as my Hornady book.  However, the Lyman book did also rate the IMR 4350 at 46 grains as maximum load and not recommended.  The recommended load was 42 grains.  Interestingly enough, the book did not list data for 165 grain bullets!  only 150, 168, 174, 180, 210 and 220.  I found that odd as I believe 165 to be more common than 168 for the Krag...  but I guess I am still learning here too.
