10mm Magnum handloading

I see that you offer the ultimate 10 here, and I've recently rechambered my S&W 610 for the 10mm Magnum, so I'm wondering if anyone has an available resource for starting loads to work up. My 610 is the 4 inch model and is primarily intended for woods carry. I have a .41 mag, and load for it, but there's enough of a difference in case size and volume that I'd be rather hesitant to use .41 mag load data directly. I've already ran across the Taffin test load date, but I didn't see anywhere in that article that shows specifics on the starting load, so I'm left to assume a start of minus 10 percent. The Loaddata.com is all AA7 and AA9. Tha Taffin and Loaddata.com info gives me at least a little something for powders that I have, notably AA7, AA8, W296, and H110, but I'd like to work up loads for some other powders I have on hand....specifically Ramshot Enforcer, Alliant 300-MP, Vihtavuori N-105, and 800-X. I shoot cast bullets (18 BHN) in the 200 to 220 grain range currently.

Anyone who has some info or resources to pass, or would care to collaborate on this endeavor, can contact me directly at meat.whiz@gmail.com.

Thanks in advance....Sean
