I was just browsing through some old Handloader magazines, and found an article in the October, 1996 issue (no. 183) on reloading for this cartridge.
There is a whole page of loads (71 loads, I counted them) the powders being used were IMR 4227, IMR 4198, SR 4759, 2400, RL7, H110 and W680. Bullet varied from 60gr Hornady flatnose to 90gr Lyman cast.
You can buy back issues from the Wolfe Publishing website, both paper copies of a lot of issues, or on cd-rom of all of them. single issues are about $5 or so, plus shipping
edit.... just looked at the website, paper copy's are $10, cd-rom are $5.95. Oct, 96 issue is available in both paper and cd
