Anyone have any load data for the SS109 62gr. bullet, using 846T AND 844 powder? I sure would appreciate it!

Anyone have any load data for the SS109 62gr. bullet, using 846T AND 844 powder? I sure would appreciate it!
My most consistent results with 62 gr SS109 have been with CCI mag primers and 25 gr. H335 (Which I think is very comparable to 844). I've tried a few different powders like H4895 and Varget with standard and mag primers, but never got the consistency (+ - 25 to 30 fps) that I get with the H335/mag combo. I've also tried H335 with regular primers and had pretty mediocre results (+ - 80 fps or so). Not surprisingly, the most consistent velocities gave me the best groups.
I'd start low and work up because H335 and 844 are not absoloutely interchangable, but you should be able to get up close to 2900 if you have an AR or Mini or something made for NATO 5.56 pressures.
